Rotate node via cel
 
Hi to every one, I have a problem with cel, i want to simulate a gear pump using a transient simulation in Cfx 11 and i want to do this by cel expression. But i can't write a expression to rotate the wall between the gear and the fluid. I can move the mesh by a traslation but i can't rotate this. Someone can tell me how i can write the expression of uniform circular motion in cel?? Thanks for the attention Elia

ok i know the mathematics equation but when i traslate it in cel expression language the solver fails and i don't know why . So i ask how i have to indicate the position in the x e y of the node with the cell expression for obtain the new position of the node from the last position. P.S. i had phone to the assistence of engin soft and they told to me that : gear pump can't be simulate with CFX it's too difficult.
