Brunoloes, thank you so much for responding. Once again my question. I can design my engine with Modelica, input the parameters and run simulations on it? Thaks for you help.

I am designing a single cylinder reciprocating engine. With Modelica will I be able to create the different parts, connecting correctly, with parameters such as force or velocity and others, make a 3D rendering of it and run a simulation of it. Any help will be greatly appreciated. Thanks.
