How to define a force, function of displacement and time derivative in Ansys transient analysis, for example the forced vibration problem of cantilevered beam with a dynamic f(x,t) force acting at free end as attached photo?
What are the advantages and disadvantages of analytical and semi-analytical methods over numerical methods like FEM and FDM? I am looking for detailed advantages and disadvantages.
