universal joint

Hello Everyone,

I have to simulate and find the pressure on the splines in the universal joint. I have to define contact surface and to find a simple method to run analysis on this joint. I am finding it very difficult to select all the surface on every spline. Also, it will make the simulation very big.

Could anyone please help me to find a method or an easy way out. Any kind of suggestions are most welcome.

 Regards

Prahel
