Hello
It has been some days and I could not find almost noting in this forum can anyone makes a discussion on this please, this has already been solved in APDL in Ansys manual I am just trying to replicate the same in Workbench as have to solve some other problems.

The whole problem is explained above. It is a three-point test. The below is the whole interface as you can see



The command is written is like following


"!Commands inserted into this file will be executed just prior to the ANSYS SOLVE command.
!These commands may supersede command settings set by Workbench.

!Active UNIT system in Workbench when this object was created:Metric (mm, t, N, s, mV, mA)
!NOTE:Any data that requires units (such as mass) is assumed to be in the consistent solver unit system.
!See Solving Units in the help system for more information.

So kindly please let me know, I will be grateful to you.

Can you sir please look into it? Thank you very much.
