Title: How to output van Mises stresses in a separate file?
Post by: zqzhang on July 26, 2017, 03:08:02 AM

Dear all,

   After searching in the whole manual, I still dont get how to output the von Mises stresses in a separate txt file or as an array.  I did not find any command, need I edit the   internal files like iofile.h?

Please, I need the answer about it. Thank you for your help.

Best regards,
ZQ

There is no specific command that will do this.  You will need to write your own user function (a UMACR*) to do this.  To see what can be done follow what we do to output nodal stresses (it is done in prtstr.f).  You can just use this to write the Mises stress (J_2 related) to the file you want.
