Dear Qishuai Zhang,

Initially, please verify that the Abaqus analysis in the Cleave fracture and Cohesive Zone Modeling examples is successfully completed. You can check this by editing the *.log file of the Abaqus analysis and see the messages inside it. After this, please check the following link for some suggestions of what may be going wrong:

Please let me know if the problem is solved.

Best regards,

George

Dear sir:

, because I am a beginner, I want to run your provide source program Cleave_fracture and consive - zone two programs, but after running for a period of time, the internal error (fig as follow), I would like to ask what is the problem, because I have changed the computer area is set to the United States , if separate executable program, step 1 can be run, please provide help me,thanks a lot!

Hello Qishuai Zhang,

Is your problem resolved now? Is everything ok?

thank you sir,i find syntax real reason ,because my abaqus version exist some bug,your M2A is very good ,thank you for your selfless sharing.

Thanks Sir‘s reply detailedly, but i still want to know these errors"

the filename, directory name, or volume label syntax is incorrect.

. " because i use your original code.

Dear Qishuai Zhang,

The output inside the Matlab Command Window that you have posted above does not contain any errors, but only warnings and various messages. It seems that in the Matlab code that you are running the instance and node set names are not properly specified as input arguments to the readNodeFieldOdb.m function. If these names are not properly specified, then Abaqus2Matlab gives the requested output (COORD) for all nodes of the Abaqus model. The first warning is issued for this reason. The two last warnings are issued because obviously there is not any nodal coordinate output (COORD) present in the odb file that is processed. However, there may be coordinate output (COORD) at the integration points of the elements, instead of nodes. If thsi is the case, then you should use the function readElementFieldOdb.m instead of readNodeFieldOdb.m.

In order to give you more details about what may be going wrong, I have to check the code that you are running, as well as the odb file that is processed. Feel free to share the relevant files if you want. Confidentiality in the various files and/or models shared with the Abaqus2Matlab work team is explicitly declared.

Best regards!
