Nice content! I got a question At 7:45 you mentioned: "Stress and displacement results associated with modal analysis can't be considered as real stresses and displacements so if you turn on it this you know I've displacement plot for the first mode you're seeing here we're getting 290 milimeters of deflection so please recognize that the mode and the mode shape and the mode frequency are accurate but the accuracy of the displacements stresses and strains is not so please disregard those if you're looking for those then then we can look at doing our subsequent analysis using a different analysis time" im looking for those real stresses and displacements. How can i get it on Nastran-in-Cad?
Please also make modal analysis video tutorial for shaft supported on bearings with cantilever load attached to it

A normal modes analysis in nastran gives me zero effective modal mass in the output file . Why ?
