I'm trying to simulate reciprocating motion for a pin on disc type test for metal to metal heat exchanges. I am new to comsol and i have no idea how to simulate alternating motion without the use of conditional logic statements. My first idea was to create a velocity Vf, and alternate it with a function Vf(-1^n). where n is based off the derivitive of a sine function = 0 based upon the radius of reciprocating over time. where d(sin(x)) = 0 = max distance from reciprocating center. However i cannot find a way to "call" in real time simulation when the derivitive of the plot of radius V Time is equal to 0, and add a summation count for n.
Is there an easier way to simulate reciprocating motion in comsol?
