Reply To: How to Create a Stiffness Matrix in APDL

Think this has been answered before - see also this link:https://www.ansystips.com/2017/10/export-stiffness-matrix-from-ansys.html

Even though it says import it actually reads/imports it from the full file say into a parameter (Matkd say) and then using the *export or *print it exports this matrix (Matkd) to a file.
again go through this example: https://www.ansystips.com/2017/10/export-stiffness-matrix-from-ansys.html
it is very good and clear - also refer to the help manual for *smat commands,..
