Hello all,
I am simply trying to solve Laplaces equation inside a Ball[] but I receive a strange error message talking about the PDE coefficient not evaluating to a numeric matrix of dimension of {3,3,3} at the origin. Any help would be appreciated!
r=5;
Rball2 = Ball[{0, 0, 0}, r];
lapball = Laplacian[T[x, y, z], {x, y, z}, "Spherical"];
\[CapitalGamma]ball =
DirichletCondition[T[x, y, z] == 100, Sqrt[x^2 + y^2 + z^2] == r];
solball =
NDSolveValue[{lapball == 0, \[CapitalGamma]ball},
T, {x, y, z} \[Element] Rball]
