I deal with a user plate element based on spectral elements to simulate wave propagation. So far my system works for a point force located somewhere in the 2 dimensional domain of the plate. Now i want to implement a pin-force like p(x,y;t)= q(x,y) f(t). That means the load acts within a region of my domain, for example a circle or a square. The command CSURFace sounds close but i think with that its only possible to locate forces to lines in 2dim problems. So far my only idea is to write a program with matlab for example in order to compute coordinates of my force region which can be transferred to the CFORCE command afterwards. Or is there a better way to do so?
Thank you very much.
