Hi all!
I am modelling a tube which acts as hyperelastic material. Inside the tube there is a fluid. Third object suppose to push this tube in one direction. Tubes edges are constrained. The problem is that when you leave no gap between pusher object and the tube, and form geometry as a union, you get a "glued" system - pusher is always bounded with a tube at the intersection point, and that way is no good. As i try forming geometry in an assembly mode other problems arise. Fluid-Structure interface boundary condition is no longer available and solver did not converge. So is there any way of simulating this kind of system?
Simulation performed without a pusher object and with a boundary load condition works, but it would be better if it would work with a pusher object.
Thank you
