Stiffness matrix from ANSYS

Submitted by rupika on

Hi All,

I want to find stiffness and mass matrix from ANSYS Classic. I found a method from internet. It is as follows.

1.Build your model normally. No need to apply boundary conditions

2. solu->New analysis->Substructuring

3.Sol->Analysis options    and give your substructure name

4.solu->Master DOFs->Define->Pick All->All DOF->OK

5.solu->solve LS

6. Click  UM->List->Other->Superelement Data     Set the name of your *.sub file, the name you defined in step 3, and set KOPT=Full Contents, then click OK

7.ANSYS will list super element data. Scroll down to:GLOBAL DOF SET NODES, LABELS=.Next ANSYS lists the order of the DOF vector for your global stiffness matrix.

But I couldn't find UM in step 6. Can anyone help me? Your help is hoghly appreciated.

Regards,
