The development of fusion systems confronts engineers with extreme loads, very short time constants and strongly coupled physical effects. With the Lawson Machine 26 (LM26), General Fusion has put a large-scale demonstration plant into operation and continuously accompanied the entire development process with multiphysics simulation. This allowed highly dynamic, non-linear processes to be mapped realistically and optimized in a targeted manner.
