Defining Center of gravity orientation

Isaac Pitti · October 28, 2014, 10:12

Hi

I'm a newbie in fluent and I am specifying a piston motion by first defining my center of gravity location based on the centroid using mass properties in DM, but I wanna know how to specify the center of gravity orientation of my rigid body using a transient profile in the dynamic mesh model, if can I write a constant input for each value? or it should be a variable input with these conditions.

Thanks for your replies

Hi again,

I have specified (in degrees)

X=0
Y=-180
Z=0

Is it a posible input?
