I am Doing Simulation through Solid edge ST7 Simulation Tool.How to check whether the results given by it is Right or Wrong ??Because we are modelling a costlier Product through Casting ...It is difficult to change the Design after casting ......
This is what a good engineer is for. CAD is not a replacement for engineering, just a tool that engineering is documented with in todays world. There is another current thread discussing FEA results.
