EVOLUTION OF PRODUCT DESIGN TOOLS
“We are truly in the era of simulation-driven engineering, an era where simulation can help synthesize and define the physical design, rather than
simply evaluate and validate a completed design.” (CIMdata - 2016)

IS IT POSSIBLE TO DO MULTIPHYSICS SIMULATION?
Ma chi può essere
Multifisico?Ci penso io!
Dai seriamente…
MULTYPHYSICS IS:
➢ Cross disciplines
➢ Requires different tools
➢ Complex!
