These days, I am trying to simulate the seismic analysis with three base excitation(two horizontals , one vertical),

Base on  the MSUP(mode super position method) I know that It can be simulated three base excitation with acceleration data.

But I don't know how to apply those seismic load in full transient analysis in workbench 2020 R1

Is it possible to do that in my ansys version? if not , could you let me know how to add APDL commend in workbench.

Please help me !!
