How to apply a moving load?

[ENGLIAO]

I was wondering if someone knows how to apply a moving pressure loading to part of model surface. Can I apply to certain number of elements at one time at one location and then shift to next location? Thanks.

Create a analytical rigid surface (a separate part) and assemble it together. The analytical rigid surface part will be the "loading patch". Create surface to surface contact between the parts and constrain/load the parts as appropriate.

Thanks a lot, Brep. But that will bring up one question. If an analytican rigid surface is tied to model surface which is deformable, will it cause deformation incompatibility?

no problem,
contact surface pairs can be
rigid vs deformation
deformation vs deformation

but not
rigid vs rigid

I have the same question like ENGLIAO. But there is a moving HEAT loading instead of a moving pressure loading. How can i do the simulation then? Thanks.

For a moving heat load I'd consider using a coupled temperature displacement analysis andhave one body as the heat source and then move that body. You can set up a contact gap conductivity so that as the gap increased, or the body moved away a certain distance, then the conductivity went to zero. A radiation type heat source would be dealt with by the distance apart between the two surfaces for the view factor given.

Thanks a lot, corus. I will try in this way.
