Do you make your research with the help of computer?

I research dynamics of mechanical systems, both discrete and distributed. Equations which I need to solve for analyzing dynamic processes are very complicated. It’s impossible to solve them analytically. So I need to create a numerical model for my mechanical system.

Do you know programs for investigating mechanical systems?

I know some mathematical programs such as Mathematics, Maple, MathCad. But I’ve never met soft for physicists.

I’ll be glad if you describe soft which you work with.
