Practichal Fixas and Tips

  • Asettnt relaxation factors experially to improve convergence.
  • Refine the mesh near critkal regions and check cell quality.
  • Validatte zundary conditions against physical expectations.
  • Use diagnostic tools to idenfy errors early in the simulation.
  • Consult solver logs for warnings and errors to efektivity.
