want to make a fatigue simulation on some mechanical parts like Gears, Bearing, and gear housing. please assume 2 gears in contact.when they Are rotating under constant torque and velocity the stress in every node is unique and varies every time. I can define a signal for a node based on time stress (\Sigma (t)) of the node but I cannot do that for the millions of them. Is there any solution for this problem? I saw some tutorial videos but all of them using one or two signals and applying to all elements but I cannot do that. Stress in posision1 (X1(t),Y1(t),Z1(t)) do not change the same as posision2 (X2(t),Y2(t),Z2(t)). But in tutorial videos stress in po1 is a constant scale of po2 in every time and the scale stays constant. please help me to solve that I have many problems with that.
