meshes interfaces 2 ?
 

Hi Rod,

thank you very muh for the answer,actually i've simulated both parts ,and they converged ,now i want to simulate the whole machine with that meshes ,but i think that a problem would arises cause to the interface ,i've used a size of 0.007 & 0.0025 on the 2 ones ,and i think that the difference is important,don't you think so ?
