I have obtained solution to a 3D FEA problem and would like to plot it on the mesh. The geometry has holes in it. For example, if u[x,y,z] is an interpolation function, obtained from a FEA solution, then is there an equivalent command to contourplot and contourplot3D such that i can plot the solution on the mesh. If i directly use the commands contourplot and contourplot3D, then the plot does not show the holes in the mesh (or geometry).
However, this function does not work because you cannot give a mesh as the domain data. I would also like to know how could i plot a 2D contour at a surface. For example something like this,
Is there any alternative to this plotting function? I would appreciate any help in this regard.
