Hi Engmost, 

Yes, it is possible. 

You can use APDL Math commands (*dmat, *smat for example) to access this. 

Please go through this link in ANSYS Help for further reference.

Also, this blog post might help further. 

Best regards,

I also can't access the help file using the link. It takes me to the customer portal login.

Students can't get an account on the portal. Fortunately, ANSYS 19.1 Help logs them in somehow.

Here is the URL after starting Help for Workbench 19.1

Here is the URL from your link:

It looks like clicking on your link should work, but it doesn't.

What does work is to RMB on the link and select Copy Link Address, then go to the browser window that activating Help from the ANSYS Workbench 19.1 opened, and paste in the address, then you get to the required page.

This seems to be a common problem, so I posted a separate discussion with the clear instructions.

Hi, I am not sure about that.

Hi, Could you let me know how can I access to ANSYS Online Help?

Best Regards.
