Dear all,

I have a question about the stiffness matrix.
Is it possible to extract the stiffness matrix of each element of a 3-dimensional structure modeled in STKEO?

Thanks in advance.

It is not possible to write the stiffness matrix of each element of a model with multiple elements.
However, if you have only 1 element, you can print the full global stiffness matrix (that in this case coincide with the elemental one, if you do not apply any constraint).

This can be done using:
printA
or
printA - file "output.txt"
