Abaqus command

If you are a windows user then you'll need a ssh client like 'putty' to have access to your remote server over ssh and a file transfer client such as 'FileZilla' for transferring large files across machines conveniently. Once you have access to your remote server you need to be familiar with some basic unix commands to be able to makeuse of abaqus via the command line.

It helps you make sense of your location on the server.

A task manager to display list of running processes. To exit use q. Some remote servers do not display the bash prompt by default which often leads to some keys not working, keys behaving unexpectedly. If that happens you may run bash from your current shell to start a bash shell. An advanced text editor which offers additional options from nano. Meant for advanced users only. To exit use :q. Oncce you have copied your input file, user subroutine file if any over to the remote server directory using filezilla, the following command can be used to submit a job remotely.

To monitor the progress of your analysis job, you can display the content of. To dynamically display the progress, you may use the tail command:.

After the pre-processing,analysis is finished you will end up with your odb file in your working directory. You can then copy it over to your machine using filezilla. In this case the data will reside on the remote computer. This is a good way to do the modelling on your personal computer and do the heavy computational work on a remote HPC machine.

There are two main steps involved in setting up remote access, namely network odb connector and remote job submission. We will take a look at both of them individually. Fill up the details of host name and directory where files are located.

In the Advanced tab, choose ssh, automatically start the server. Choose a lower time-out of minutes. TO connect to remote directory, click open and browse to the Network Connections. Here you should find your remote directory. This is merely an example, the parameters would change according to how you would like to submit your job.

Remember that queueName should be identical on both machines. The local machine would show name as submission queue but the job would be submitted to the queue named myqueue. Coming from Windows If you are a windows user then you'll need a ssh client like 'putty' to have access to your remote server over ssh and a file transfer client such as 'FileZilla' for transferring large files across machines conveniently.

Lists available options for that particular command. Use the Up and Down keys at the terminal to go through your command history. Saves you from retyping the entire line again and again.An environment file must exist in this directory. The settings in this file are ignored when a job is submitted to a remote queue. Instead, the settings in the site subdirectory on the remote computer are used.

The user's home directory. This environment file is optional and will affect all jobs submitted from the user's account. The current working directory. This environment file is optional and will affect all jobs submitted from the current working directory.

Attempting to use a Version 5 format environment file will cause errors. The following syntactic rules also apply: All parameters are case sensitive. Comments are preceded by a number sign. All characters following a number sign on a line are ignored. Number signs within a quoted string are part of the string, not the beginning of a comment.

Lists must be enclosed in square brackets [ ]. Individual items in the list are separated by commas. Tuples must be enclosed in parentheses.

Individual items in the tuple are separated by commas. If the tuple is enclosed in parentheses and contains only one value, a comma has to follow the value.

Embedded single quotes do not require special handling if they are placed within a double-quoted string. For example, "my value's" is translated as my value's. The same holds true for double quotes embedded in a single-quoted string. Strings in a list or a tuple must be enclosed in quotes.

Triple-quoted """ strings can span more than one line, and no special treatment of quotes within the string is necessary. Settings from the earlier release may not be compatible with the new release.

The available parameters are described in the following sections. The available units for memory sizes are mb megabytes and gb gigabytes. If the units are not specified, the size is assumed to be in megabytes. The default value for Windows bit systems is MB. In this case the limit can be changed to MB. For optimal performance, the memory limit should be set to a value less than the physical amount of memory on the machine.

During the analysis a subdirectory will be created under this directory to hold the analysis scratch files.Abaqus is used in the automotive, aerospace, and industrial product industries. Abaqus also provides a good collection of multiphysics capabilities, such as coupled acoustic-structural, piezoelectric, and structural-pore capabilities, making it attractive for production-level simulations where multiple fields need to be coupled.

Abaqus uses a traditional implicit integration scheme to solve FEA and uses an explicit integration scheme to solve highly nonlinear transient dynamic and quasi-static analyses.

You can take advantage of Rescale's ScaleX platform and its simple workflow to run complex and large Abaqus models in batch mode. This is a standard benchmark problem on Abaqus - a mildly nonlinear static analysis on an engine block. The model simulates bolting of a cylinder head onto the engine block. Yielding of the gasket accounts for the non-linearity of the simulation. This is an explicit benchmark problem on Abaqus - a car crashing into a rigid wall at 25mph. The car is modeled with a von mises material with isotropic hardening.

This is a standard benchmark problem on Abaqus - a strongly non-linear static analysis of a tire footprint. The model simulates mounting the tire onto the wheel, inflating it, followed by vertical loading. Large displacements, sliding contact and hyper-elasticity accounts for the non-linear nature of the model.

User-Subroutines allow users to customize Abaqus capabilities to their need. For example, we can use subroutines to define material properties e. The example used here is a standard benchmark Abaqus simulation that uses user-subroutine DISP to prescribe the boundary conditions. The job setup includes three input files:. The job setup and results of this example are attached below. Cylinder Head Bolt-up Example This is a standard benchmark problem on Abaqus - a mildly nonlinear static analysis on an engine block.

Static analysis, followed by 2. Dynamics Analysis Description Static and dynamics analysis with sinusoidal surge motion boundary condition prescribed using User-Subroutine in Abaqus on Rescale.Provide default values for job parameters that would otherwise have to be given on the command line.

The user-level environment settings. The job-level environment settings. Environment settings can be specified more than once. The last value processed will be the one used for the setting if it is defined at more than one level or if it is given twice at the same level. The host-level settings are set in the site directory in the abaqus account directory. Settings in the home directory file will be applied to all jobs that you run.

Overriding the default setting may occasionally result in improved performance. It is also possible to set this option on a step-by-step basis within an analysis. The value specified in the step overrides the value specified on the command line or in the environment files.Usually what most Abaqus users will do, in order to submit an analysis, is to create and submit the respectful job file when their preprocessing stage model is complete.

This process is done in most cases through Abaqus CAE. Subsequently the user will track the job monitor accessible through the Job manager in order to acquire valuable information regarding model related warnings and convergence performance of the solver. However, there is quite often the need to submit a job file from the command window. The main reason behind this action, might as well be one of the following: ability to run several jobs simultaneously or sequentially, token re-allocation for extra CPUs in place of the CAE if the total number of tokens are limited, or if there are multiple Abaqus users occupying tokens etc.

For our example, we have setup a cantilever beam problem. One side of the beam is fully fixed and a pressure load is acting on the beam as shown in Picture 1. Picture 1 - Setup Multiple Loadcases for cantilever beam. So let us assume that are model has been set-up correctly in the pre-processing stage. What is always good to do prior to submitting the analysis or in our case prior to writing the input file for submitting the analysis via the command window, is to perform a data check.

With this action, Abaqus checks that the preprocessing part of our analysis is indeed well-posed. The data check option is shown in Picture 2. Picture 2 - Datacheck for preprocessing. Open command window here. When the data check is complete, several files are created within our assigned Abaqus work directory.

The content of those files will be explained in comparison with the job monitor. The action of writing the necessary analysis file the. This file will then be available in our work directory. Submit job through command manager. Next we are ready to submit our job for analysis. These files are explained below in comparison with the available output from the Job monitor.

Dark Mode Beta - help us root out low-contrast and un-converted bits.The abaqus restartjoin utility appends an output database.

A similar utility, abaqus appendis used to join results. See Joining results. You can append output database files from analyses that restart between steps and from analyses that restart in the middle of a step. While the required syntax is the same for these two types of analyses, Abaqus appends data differently, as follows:. For an analysis that stops and restarts between steps, Abaqus simply appends the output from the new steps to the output from the existing steps of the original analysis.

For an analysis that stops and restarts in the middle of a step, the original and restart analyses overlap because the restart analysis resumes at the beginning of the interrupted step.

In this case the abaqus restartjoin utility retains the results for any completed steps in the original analysis but replaces the results for the interrupted step with the output data produced by the restart analysis. By default, Abaqus appends the output data produced by the restart analysis directly to the original output database file.

If you prefer to retain the original output database file, you can create a copy of it and append the restart analysis output data to the copy instead. Abaqus omits history data when you combine original and restart output databases; however, you can override this default.

You can also control whether Abaqus compresses the combined output database file. This option specifies the output database file produced by the original analysis. If you omit the copyoriginal option, Abaqus appends the output data from the restart output database file directly to the original output database file. If you omit this option from the command line, Abaqus will prompt you for its value. This option specifies the output database file produced by the restart analysis.

You can specify only one restart analysis output database file at a time. If this option is specified, Abaqus creates a copy of the output database file specified by the originalodb option and appends the contents of the restartodb output database file to that copy instead of to the original file. When this option is omitted, Abaqus appends the output data from the restart analysis directly to the original output database file.

abaqus command

If this option is specified, Abaqus copies history data from the restart output database to the original output database or its copy. Abaqus omits history data in the joined output database file unless you specify this option. If this option is specified, Abaqus compresses the resulting output database file. If your model produced an initial output database file named Job If you prefer to retain the original output database file, you can create a copy of this original file and append the contents of the restart output database file to the copy instead.

To perform the restart join operation using a copy of the original file, issue the following command:. By default, Abaqus does not copy history data to the combined output database. To include history data, issue the following command:. Appending data when the analysis restarts between steps versus midstep You can append output database files from analyses that restart between steps and from analyses that restart in the middle of a step. While the required syntax is the same for these two types of analyses, Abaqus appends data differently, as follows: For an analysis that stops and restarts between steps, Abaqus simply appends the output from the new steps to the output from the existing steps of the original analysis.

Customizing the combined output database file By default, Abaqus appends the output data produced by the restart analysis directly to the original output database file. Command summary abaqus restartjoin originalodb odb-file-name restartodb odb-file-name copyoriginal history compressresult.
