[0.4.1] - 20230725

Solver

• Now reading constant thermal properties and initial conditions. First thermal-mechanical example ready.
• Fixed Friction Stir Welding example (greater particle density results in not so negative temp at the begining)
• Added input reading details (to know in which vars exists an input error)
• Randles and Libersky variable time step integrator working
  Input File
• Nb frequency update option on input
• Changed Sjohnson Cook constant order
• Added Cylindrical grid option in input
