I know these calculations in thermodynamics can be done by hand or a simple calculator but I wonder if some programs do these calculations. These programs might be called multiphysics programs. An example of a calculation - select piston-cylinder arrangement. -enter initial volume and pressure; P1 V1 - enter final volume and polytropic exponent - calculate work done This calculation can be performed in numerical analysis programs or CAS but can multiphysics programs have an advantage? Thank you.
