Dear Abdellah,

Could you send me the Matlab code at gpapazafeiropoulos@yahoo.gr? In this way it will be easier for me to check and run it.

Best regards,

George

Dear Abdellah,

It seems that stepName, nsetName and instanceName are case-sensitive.

Please specify the following commands in the Matlab script and then rerun it. Please let me know if the problem is resolved.

stepName='STEP-5'; 
nsetName='SENSORS'; 
instanceName= 'PART-1-1' ;

Best.

George

Hello George,

Thank you so much for your generous and kind support!

The issue is not resolved. I tried it and did not work. I have the same issue. It does not find the node set.

The input files, generated using Hypermesh, are not organized into assembly, parts and instances. The problem may be related to that. What do you think?

I really want to use Abaqus2Matlab to post-process the data, though I would be able to do it via Abaqus.

Again, thank you so very much!

With kind regards,

Dear Abdellah,

Please replace the following command in the Matlab code that you are running:

instanceName= 'False' ; 

with the following command:

instanceName= 'PART-1-1' ;

Let me know if the problem is solved. Thank you in advance.

Best regards!

Dear George,

I am pleased to forward to you the script file and a picture of the odb visualization in Abaqus to see that the node set sensors is indeed present. Maybe the name has changed or it has something to do with the assembly, parts and instances. I am unable to upload the script file. Below is a copy:

Hello George,

Thank you so much! I will look at it and come back to you.

Thank you immensely! With kind regards,

Dear Abdellah,

Thanks, you too!

Obviously there is a problem with the syntax of the function readNodeFieldOdb (line 76 of the Script_job2_A2M.m file). You have to ensure that the input arguments that you specify for this function are correct by checking if they exist in the odb file that is processed by the function.

You can send me the file Script_job2_A2M.m and the odb file that you are trying to read if you want. Confidentiality in the various files and/or models shared with the Abaqus2Matlab work team is explicitly declared.

Best regards.

Dear George, thank you so much for your very kind prompt reply and time!!!

The issue is fixed. However, I am still have warning. It looks as though it does not find the node set sensors in the ODB file.

Hello,

Thank you very much for your kind comments.

Please try the following:

(1) In the file Script_job2_A2M.m, line 78, try to replace the following command:

POR =readFil([ Inp_file '.fil' ], 18 );%Obtain the  Pore or Acoustic Pressure(POR);

with the following command:

POR =readFil([ Inp_file '.fil' ], 108 );%Obtain the  Pore or Acoustic Pressure(POR);

Then rerun the file Script_job2_A2M.m and check if the pore pressure output is extracted.

(2) Check if there is an option in the Abaqus input file for output to the fil file. The options:

*FILE FORMAT, ASCII
*EL FILE
 POR

must be specified in the input file in order for your Matlab code to work properly.

(3) If the options in (2) have been specified correctly, please check the data line of *EL FILE option if two or more incompatible types of output are specified. You can also see if this happens by editing the Abaqus dat or msg files and checking for warnings about variables that will not be printed in the results file.

Let me know if the problem is fixed.

Best regards!
