Dear NGSolve community,
Is there a (efficient/clever) way to use CoefficientFunctions (VoxelCoefficientFunctions) as indicator functions to define subdomains? Hence, having a 3d volume/mesh and define different domains (materials) according to the value of the CoefficientFunction.
I assume it is similar to the explanations in stl file contains multiple parts / individual material parameters needed, where the element index is set using some coordinate criterium.
Thanks!
Chris
