Hi,

 

i am trying to extract a StiffnessMatrix of a whole Car Model using DMIG.

While creating the Model I followed the Tutorial: OS-2070_ Topology Optimization of a Reduced Model using DMIG

 

when i start the Analysis to get the .Pch Data there is an Error:

 

*** ERROR # 826 ***
 Invalid subcases have been used in this ASET run.
 In ASET run, all subcases must have the same SPC and MPC set.
 Subcase 1 has SPC set 1
 Subcase 2 has prepaset set 2

 

Does anybody know, how i can fix the Error?

    Is it possible to send just some screenshots?

    If yes, let me know, which screenshots you need.

    Hi Mak,

     

    From the erorr message I can make out that you are using two sets of ASETs for two subcases which is not allowed according to error.

     

    So you need one ASET
