Hello,
It must be trivial, but I cannot find what's wrong in the model.
The purpose is to perform modal analysis of a SDOF system with concentrated load at the top of 500 kN.
The self-weight shall be ignored. In Modal analysis case the SW is disregarded, and only load case 1 is converted to mass.
It seems that it cannot accept the concentrated load and convert it to mass.
Though, it works for selfweight only if I uncheck 'Disregard density'.
The file is attached below.
