Valve deflection
well trying to go through the process of using FEA to solve cad drawings for Stress strain and deflections This means I can conceptualize an Idea run it and check then send straight to rapid prototyper/ water cutting or Machine shops I am using CAELINUX ( Salome post processor, ASTK solver ), while this is free open source , its in french . I dont speak french!!! Still I ve managed to, model the piston and a valve. So I can now epand on the idea. Stephen
FEA 1
Finally got a FEA package to easily ???? run a script. Using a tutorial I managed to load, mesh , solve and display a piston. Now I know How , and the pitfalls , I can start modelling other parts such as a foot peg bracket A couple of minor question remain but they are solvable Stephen
