Hi guys, I'm modelling an hole in a thick wall whit a flow through. At x-time, the hole become wider. How can I stop the simulation, change the boundary shapes, and restart it? Thanks, luca.

Interesting to know how it is possible. So it is unsteady calculation. Now, the question is how to widen the hole diameter during the calculation.Or is it that the diameter of hole changes only at perticular time x?

It would be just a valvle: initially close, and open after that pression gets a particular value. At this moment, it's not important to represent opening phase (later, we'll see...), I just want to understand if it' possible to change geometry and restart iteration.

Thanks.
