I wanna simulate a problem with GMO model. Fluid can wet one surface of the rigid moving body , the other faces can't be wetted. So, how to define the different contact angles to each surfaces within on component?

use two sub-components defining the GMO component. Each sub-component can have a unique contact angle. The input variable is CANGSUB(n) for a sub-component #n, I think.

Thank u, MuxaB. But Flow3D have not afford the input variable CANGSUB for defining the contact angle for sub-component. There is only CANGLE for component in version 9.3.

I have thought using different components to define the rigid body. But i have no idea that how to make these components moving together. :-D

you are on the right track. it is easy to make two components move together if they both have prescribed motion - just define the same velocities. Not so for the coupled motion case.

How come you use an older version?
