Generate a metric tensor (3x3 matrix) filed from a scalar field defined on a input tetrahedral mesh, which can be used in mesh adaptation.
Input TempName.vtk and TempName.sol, MeshMetrix will output TempName.o.sol
$ MeshMetric TempName
Input TempName.vtk and TempName.sol, MeshMetrix will output TempName.o.sol and TempName.o.vtk
$ MeshMetrix -v TempName
