Default Problem of changing boundary conditions
Posts: n/a
Hello everyone,

I am trying to solve a problem including two phases. In one phase, methane is injected in a fluid volume with the interface between it and another fluid volume being defined as wall boundary condition; then in the following another phase, I change the ˇ°wallˇ± boundary condition to ˇ°interiorˇ± boundary condition to allow the mixture in the former volume filling in the latter volume. But when I tried to continue the calculation after I have changed the boundary condition as above, an error occurred as ˇ°pressure correctionˇ±. Any expert can give me some advice about it?

Thanks in advance!

You may have to specify the old wall as 'interface'. This requires you have a pair if faces on the border of the two domains.
