moving ground BC?
 
Hi everyone...

Could someone confirm If i could set a moving ground boundary condition in Starccm+, if its possible, how do i implement it?

thank you
:rolleyes:

That's pretty simple. Just go to the boundary -> Physics Conditions -> Tangential Velocity Specification and set it to vector. Then you can go to the Physics Values and enter the velocity vector there.

Hi Abdul099

Thanks for the reply....could you please be a bit more specific.Once i go into boundary>physics condition the only thing im offered is initial condition option...is there something else im missing....i would really appreciate if you could help me sort this out since ive spent quite sometimes trying to figure it out....

thank you:)

Dear ACER,
You need to go to a specific boundary ( such a wall) in your region that needs to be defined as a moving boundary.
