- The system equation is [K]{x} = {F} with perhaps a few added terms here
- and there. Since you've solved for {x}, and you can form or retrieve
- [K], you _should_ be able to do the matrix multiply.
-
- OK, that's the theory. Now the ANSYS experts can jump in and tell you
- how to access [K] & {x}...
