1. Use `example/top-thermolastic-compare-3d` to run mechanical(Me)/mechanical thermal(MeTh) topology optimization(Top) and simulation(Sim).
The procedure run in following order:
1. Me Top & MeTh Top -> density(*_MeTop_rho.vtk & *_MethTop_rho.vtk) and compliance/volume each iteration(*_MeTop_compliance.txt *_MeTop_volume.txt & ...)
