Hi,
I installed Code_Aster version 17.4.
The spectral analysis (operator COMB_SISM_MODAL) seems much faster, which is a great improvement.
However, the calculation of the absolute accelerations (OPTION = 'ACCE_ABSOLU') doesn't work anymore for multi-level earthquakes (TYPE_ANALYSE = 'MULT_APPUI').
This is very annoying because absolute accelerations are needed for the verification of components like valves.
Is there any workaround for getting the absolute accelerations ?
Thanks
