Modal analysis with concentrated load

mabefa

Hi, 

By the theory of the dynamics of the mechanical system I know that a modal analysis is done without loads because his purpose is to find the normal modes of a body, but I've been asked to make a normal modes analysis in HyperMesh on a component which has a concentrated and constant load of 800 on it. How can I include this load in the loadstep to set and run the analysis?
