Rotational inertia of nodes with 6 DoF ommited in (.full.mat) file
Dear all,
I am extracting the mass matrix of a structure modeled with shell elements (CQUAD4) using OUTPUT,MATRIX,FULL,SPARSE. However, the rotational inertia corresponding to the nodes (with 6 DoF) is omitted in the .full.mat file.
Below is an example of the results I am getting, for a lumped mass matrix, where the rotational inertia (Ixx, Iyy, Izz) for node 1 are missing (which would correspond to missing the headers: '4 4 4', '5 5 5', and '6 6 6', that are omitted).
Please let me know if you any idea how to solve or go arround this problem.
Best regards,
Pedro Millan
