How to read spatial-dependent Young's modulus into Materials?

[zhang-rite]

Hi

Could anyone tell me how to read spatial dependent Young's modulus values from a file into materials?
As referring to an example in Porous media module, I know how to read values for permeability field to materials through
PiecewiseMultilinear -> FunctionAux -> PorousFlowPermeabilityConstFromVar
But doing the same for Young's modulus seems does not work using ComputeVariableIsotropicElasticityTensor. Any example (code)?
Thank you.

Oh, after posting this question, I just become lucky!
To solve the problem, one may just add a ParsedMaterial to bridge the FunctionAux to Materials.
Perhaps there is a better solution?
