Internal Programming error in Optistruct

clear all previous files in work folder (close hyperview if it is opened).

check penetration.

Hi,

• Tried changing the working folder, No hyperview session is opened.
• No Penetration in the model. 
• I need to know whether it is a modeling error or memory error. (Waiting for your reply)

could you show .out file?

 The realization of node-to-surface contact at large displacements is not
 exactly the same as in small displacement (NLSTAT) analysis. No internal
 CGAP/CGAPG elements are created in the large displacement case.

 The structure of surface-to-surface contact element is quite different than
 that of node-to-surface contact element. No internal CGAP/CGAPG elements are
 created for surface-to-surface contact.

 The total number of rigid elements, whose rotational dependent d.o.f.
 are removed because there is no need to constrain those d.o.f., is 2.

have you tried to solve part of model? Has it gone?

maybe it's so large for your computer?

Yes the element count is more,  so you summarize to be the memory issue? if it is so, is there any solution to make it run?

Almost 300 GB space is available in my drive.

try to solve reduced model/part of model.
it's difficult to search mistake in large model.

Hi @Chethan Y C

Can you update the solver to the latest available and check if that helps?

Most of the programming errors are solved in updates. 

Hi,

 I have updated the solver to 17.2, but the issue remains the same.

Hi @Chethan Y C

Can you share the model file, please?

Please use the file transfer link in my signature to share the model file

• Sorry, i am not supposed to share the model. 
• The model has hybrid meshing (Hexa, pyramid,tet), does it cause a problem?
• <?xml version="1.0" encoding="UTF-8"?>

Can you share the .out at least so that I can check with developers? 

Hi,

The .out file is already shared(Previous replies).

Hi @Chethan Y C

I need the .out and .stat (TEXT files) to share with the experts.
