Hello FOAMers!
I am trying to simulate something like an explosion in an open field. It's a 2D simulation with the explosive on the ground. The explosive is simulated as a "balloon" with high pressure. Although, this is the error I get: Quote:

[QUOTE=Calmly;664350]Hello FOAMers!
Hi, Calmly Have you solved your problem? I'm not sure where the exactly the problem are, but with this high compressible problem, I would choose the upwind or the limitedLinear in the grad schemes. |

The boundary conditions doesn't seem right to me. On the sides I would suggest to use fixedFluxPressure for p and inletOutlet or slip for U, assuming that sides are far enough from the region of interest.
pressureInletOutletVelocity is used when pressure is prescribed in the boundary. Also, I suggest to use upwind for schemes at first to make sure model works. Once you get reasonable results you can use higher order schemes. |
