Element matrix output cannot be requested in a mode-based dynamic analysis (response spectrum, steady-state dynamic, modal dynamic, or random response). for: ***** program Extract c *** primary function: Extract global mass and stiffness matrix from full file. The Nastran data must be in a file with the extension. Cantilever boundary conditions can also be modelled by constraining all degrees offreedoms of the nodes located on the left end of the beam. This function computes the 24x24 stiffness matrix for a regular 8 noded hexahedral finite element of arbitrary dimensions. Export the ansys stiffness and mass matrix to text files Directly type in the commands into a text file from scratch.
