Hello

I was wondering if someone could help me out.

At the moment I have the CG_MOTION udf and specifying velocity as
vel[0] =1. I need the velocity to travel to the end of my domain and then to reset to the begin point and travel again and again and so on

can someone please help me with this???

I also have to define the interaction of air and water. For this using the vof model. When I do it as the tutorial say I gat the whole domain as either water or air but not a defined line between the two?? Can someone please help me?

Thank you

Hi,

I don't really get the first part of your question but for the second part you can use the Adapt --> Region to mark a region that will be filled with water.
After initialization you can use the patch option, you have to choose the 2nd fluid material and patch it on the region you just created (under registers to patch)
