Thanks again. Just to add, shift+tab will remove the indentation when editing the script...7:30, also you can write from abaqus import * from abaqusConstants import * from caeModules import * to get rid of all the import statements and reduce the line of codes. You could also initialize all the dimensions and mesh sizes to parameterize them. Thanks always for your videos
Hello @Jide Williams, thanks for the comments. You are absolutely right. I didn't want to go into anything complex but your comments are correct. Thanks.
Hello Dr. Michael, thank you for the very good content on your youtube channel. I was automating a model on Abaqus, and when I reached the part of reading the results from the .odb file, I encountered the following error message: ``` from odbAccess import openOdb ModuleNotFoundError: No module named 'odbAccess' ``` Is there a possibility to analyze the .odb file directly from Python? I am running Abaqus jobs in batches and do not want to open every .odb file in an Abaqus CAE window and run the Python script there. Thank you in advance, and I look forward to your response.
Hello, This is certainly possible. In fact ABAQUS documentation has an example which you can adapt for your case. Here is the link to the example: classes.engineering.wustl.edu/2009/spring/mase5513/abaqus/docs/v6.5/books/cmd/default.htm?startat=pt01.html You may have to consider this: from odbAccess import openOdb odb = openOdb('job_name.odb') I think it is possible to analyze .odb file directly from the ABAQUS command window. I am not sure about running it directly inside Python - but if so, then you do need to import the right object files, which it seems to me this is what is happening with your error. I suggest you run it inside the ABAQUS command window or the ABAQUS kernal window (located foot of ABAQUS CAE page). This way, ABAQUS already has the object files like the odbAccess, so you do not have to worry about them. If you run inside Python, you will have to worry about where they are and bring them in. I hope you are able to do it.
@@MichaelOkereke Thank you for your response Sir. Actually, I was able to extract the results and complete the entire process outside of Abaqus using just the external Python interpreter. I used the following command: command = sprintf('abaqus python extract_results.py %s', odbFile); [status, cmdout] = system(command); Instead of just "python extract_results.py", and everything worked perfectly

Hi Dr. Okereke. Thanks for these amazing and helpful videos! I have a question related to creating Sets (Type: Node) using python script. I want to create sets (Type:node) for specific nodes. I have their label and coordinate. How can I create these Sets using either the node coordinate or label via script? I tried to use Macros, but I don't understand it. This is what the Macros shows: nodes1 = n1.getSequenceFromMask(mask=('[#0:2 #2 ]', ), ) a.Set(nodes=nodes1, name='left_3') Is there any way that I could use the coordinate or label to create these sets? Thanks and good luck!
Hello David, I think this is possible. It is about understanding the right commands to use in Python to extract the mesh array that will help you assign the required coordinates to the nodal set you mentioned. The use of macros in this instance will simply help you understand the sequence of Python instructions that can lead to a possible solution but the key problem is 'getSequenceFromMask'. It is a user-intervention command rather that truly being automated as you would. I will not go with that. I will rather investigate this further. I have not given much thoughts to it but I cannot see why this is not possible. Good luck with your research into this problem, does sound interesting.
Nice video, I am a new joiner. Can you share any info. on how to create a parametric study in a loop. And how to take a stress and strain of a specific node without manual interruption in GUI. THanks in advance.
Hello @Rakshith B D Gowda, thanks for joining. Welcome to the CM Videos family. Please see other videos on the channel as you may find them helpful too. 1. On Parametric study within ABAQUS, this will be added to my to-do ABAQUS tips and tricks video. I think it will definitely be helpful to many so I will consider making such a video in future. 2. For the second query on a non-GUI based interpolation of ABAQUS data (I suppose you mean based an output databas file), this is something I have thought about in the past. I have a few videos on my ABAQUS Tips and tricks playlist which address plotting stress versus strain plots from simulations but all of them are GUI-based. I have always wanted to make one more video with a non-GUI base which will be probably done using a Python script. I will note this request and see if I can do such a video in future.
Thankyou Dr. Michael. Could you help me in writing script for .step file from solidworks which is to be imported into Abaqus so that I could perform Parametric optimization in Isight Module? Would be really thankful to you for this
Hello Muhammad, this sounds like a lot to do I a single video. I am not be able to help with the query. Can you simplify what is requested here so I can consider if there is any merit in doing a video about it?
Hello @David, I think you can do so by following the strategy of this video. Setup up a macro and create a triangular mesh on a model. Then from the resulting macro-created python script, you can see the commands for automatic creation of a triangular mesh. Then repeat this in your code. I hope this helps.
Hello Dr. Michael Okereke Thanks for the video. And I want to know how can we export or convert from the existing ABAQUS file to the Python scripting file?
Hello @Sothun, normally it is the other way round. You get a python script to create an ABAQUS file. If you already have an ABAQUS file, you might not easily create a python script with that. What I tried to show in this video is that you can record a macro file when carrying out an ABAQUS model setup which you can subsequently use to recreate the model. Also, if you did not do so, then check in the folder where your job is saved and you will see a Journal file (*.jnl) which you can use to recreate the model. This is a feature of ABAQUS but not available with a student license ABAQUS.
@@MichaelOkereke And when I use *.jnl file to recreate the model then do I have to record the Macro as what you have done in the video right? By the way, how can I run the *.jnl file in the ABAQUS?
Hello @sothun, you run the *.jnl file by opening ABAQUS CAE and then File > Run script ... and from the pop up window, navigate to where the *.jnl file is and select it and click Ok.
hi, can i use a hyperfoam material in the python script which is based on 2000 test data? it seems like it is not possible to link the json file into .py-data and run in abaqus. do i have to dump the test data in the .py data to run in abaqus? or is running the script with noGUI-Task directly in python an option as well? How would you define the hyperfoam material? Do you have any documentation i can take a look into? greetings!
Please see the Pinned comment (at the top of the comments section) where a commenter on this video stated how to removed the spaces different from my method. It involves (on Windows) using the Shift+Tab option. Just put your cursor where the space is and press Shift+Tab and it will delete the space automatically. Of course, if you want to select all the spaces at once, then use the method I showed but with deleting, you can use the Shift+Tab option. Please try that!
hELLO @Miguel, I am not sure if I understand your query correctly. Python is used to command ABAQUS to do things for you, so it seems to me you will have to get a Python code to determine what you intend to do.
I have a Python script with everything needed to simulate a theoretical scenario. What I am looking for is to automate the process with Python, so that it does different simulations for me by varying some parameters. That's why my question is: having the python script already complete, how can I program in Python in such a way that when executing the code, the script is simulated. I understand that the code to call abaqus in Python is abq2019 job=name.inp -double -int
Hi @Miguel, now I understand. It sounds like you need to do a nested script with your main complete script called by another script. It is possible you make the first script a function which will be called by the running/simulation script. Alternatively, since what you really want to do is to automate the process, if you are running it on say a UNIX platform, you can use a shell script to batch the running operation. I have done this in the past. If this will help, here is the snippet of code that you can put at the end of your script for submitting the job to run automatically. I have done this with a model of mine called: "HexagonalModelUpdated_UniaxialX", just replace it with your model name: #-------- Submit job for running -------- mdb.Job(name='HexagonalModelUpdated_UniaxialX', model='HexagonalModelUpdated', description='', type=ANALYSIS, atTime=None, waitMinutes=0, waitHours=0, queue=None, memory=50, memoryUnits=PERCENTAGE, getMemoryFromAnalysis=True, explicitPrecision=SINGLE, nodalOutputPrecision=SINGLE, echoPrint=OFF, modelPrint=OFF, contactPrint=OFF, historyPrint=OFF, userSubroutine='', scratch='') mdb.jobs['HexagonalModelUpdated_UniaxialX'].submit(consistencyChecking=OFF)
Hello @Benmeddour Amor, thanks for your interest in the channel. I do not think it is possible to create a **.CAE* file from a **.inp* file. The INP file is just a list of instructions for the FEA solver to use in creating the solution. It does not have the capacity to genate CAE files. You can however, open the INP file in ABAQUS by importing it as a Model. This will create an orphan mesh which you really cannot edit. However, here is a video by another excellent Computational mechanics guy which shows how you can change orphan mesh into a model. YOu can then take the model and re-mesh it into what you want.
