Dear all,

I performed the elastic simulation on a three-dimensional cube in FF++, using parallel computing mode (load “PETSc”). When I used two processors, the FF++ code is normal. However, as I used four or more processors, FF++ reported the error, i.e., Argument out of range. Was it because my computer configuration is too low?

Please give me some advice. I would appreciate it.

Best regards,  
Liu

You need to share the code that is giving you the error, otherwise it’s difficult to help you.

The following code should run to completion.
