Hello Team, Is there any way to get modes of coupled fluid-structure in modal analysis (example : fuel tank 90% filled condition) ?

    Hi Shritej,

    You can look at the using MFLUID option in OptiStruct.  This can be used to include the effect of virtual fluid mass on the normal modes for partially filled containers like fuel tanks.

    Thanks,
