Errors in reading ODB

First of all, the .fil is not getting created when time points are introduced along with nset. If I want to extract directly from odb using ReadFieldOdb command, the flollowing errors are encountered.


true must be True or False

Error in error (line 16)

Error in readNodeFieldOdbPyScript (line 184)

Error in readNodeFieldOdb (line 252)

readNodeFieldOdbPyScript(odbFile,stepName,instanceName,nsetName,...

Error in Main_CODE (line 24)

[odbOut,odbDat,~]=readNodeFieldOdb('soundtemp_optim.odb','Step-1',...

Hello shaunakchat,

Could you please post the entire Matlab command in which the function readNodeFieldOdb is called (i.e. line 24 of Main_CODE.m)?

Also, are you running Abaqus/Explicit? If yes, could you please post the *DYNAMIC option inside the Abaqus input file?

Best!

In the Matlab script Main_CODE.m, please replace the command:

[odbOut,odbDat,~]=readNodeFieldOdb('soundtemp_optim.odb','Step-1',...
    'gfrp-1','node','NT','true');

with the following:

[odbOut,odbDat,~]=readNodeFieldOdb('soundtemp_optim.odb','Step-1',...
    'gfrp-1','node','NT','True');

Let me know if it works.

Thank you very much for your help, the error is gone, but I cannot understand the results. I have specified the nset=node in the code and input file, but it seems the results are coming for all nodes.

@shaunakchat If the instance 'gfrp-1' does not contain a node set called 'node', then Abaqus2Matlab processes the results for all nodes of the model. Please check the Abaqus input file for the node set definition. You can post it here so that I check it as well.

@George Papazafeiropoulos Yes, the node set 'node' is defined in the assembly. So what will I write in the instancename? I am trying to upload my input file, but an error is showing here.

I am still getting the following error:


Incorrect class for expression 'indOut': expected 'char' but found 'logical'.
