How do I model a two-variable sinusoidal load?
How do I model a two-variable sinusoidal load?
(OP)
I have an isotropic plate of shell elements that is simply-supported in the xy-plane. I'm trying to model a sinusoidal pressure in the +z-direction of the form:
P = sin(pi*x/3) * sin(pi*y/3)
where "x" and "y" are my variables.
I have a feeling that if I go to MODEL ==> LOADS ==> ON SURFACE ==> FORCE/AREA ==> FUNCTION (while keeping only the Fz box checked) that I could specify my load there. Unfortunately, it appears that this would only work for a one-variable case. Even in that case, I am having trouble understanding how to go about that. Please, can anyone help me solve this problem? I would really appreciate it.

another thought, maybe a little easier ... integrate the function for each element, then at least you don't need to fuss the mesh, and apply the load as a uniform pressure on the element. mathcad or maybe excel should be able to do it; maybe exercise the grey matter ...
