(* suppose a finite element run generated a solution u[x,y] with the \ command listed below*) ufun = NDSolveValue[{op == Subscript[\[CapitalGamma], N1] + Subscript[\[CapitalGamma], N2] + Subscript[\[CapitalGamma], N3],...
Ok now I see the reply from Keith. Thanks David
Thanks for the answer!! I would like to force the high and low color cutoffs of the function being plotted so that when I compare two similar plots, red, blue ...etc means the same numerical value in both plots. How would you do that? Thanks...
I cannot get the "DirchletCondition" type boundary condition to work on a simple 2D pde heat equation . I can get it to work by explicitly applying the boundary condition like u[x, ylow] == ulow, u[x, yhigh] == uhigh for two opposite straight...
