SRS and Internal Pressure

I have a Pressure Vessel I need to verify for SRS (Shock Response Spectrum). When I try to combine SRS with static load with Internal Pressure I get the error message *** ERROR # 1461 *** in the input data:
Card "STATSUB(PRELOAD)" is not allowed for this subcase type.

Can anyone help? Thanks:-)

    Hello Bernt, 

    Currently (V2022), SRS analysis does not support preloading. A workaround here would be to run a transient analysis (using a half-sine curve for example) instead of SRS. THis way you can use the static analysis as preload. 

    Thanks,
