Hello; I'm a student of preparatory class for high schools, and I have to do a project to go into Engineer school. This project is to recover thermical energy from the road, and transfer it to heat bridges, or sidewalk. The problem is that i have to do some simulation and experimentation of my project, and i don't have any idea how to do that. That's why i need your help to have a simulation software to simulate and calculate the reheating of a bridge. Thanks you, Timothey.
