Dear all,

I'd like to simulate a nozzle jetting, I have tried the tutorial of dambreak. I use the dambreak as template to do the simulation, but it failed. The following is the two models: one is with nozzle, the other is without nozzle. and there's no input flow or pressure on the inlet boundary.

the problems are

1) the two models are the same, except the geometry. why the model w/o nozzle is successful when simulating, but the other one failed.

2) what means can improve it?

Thanks.

Best regards,
Martin

I don't know if this is your only problem, but if you run checkMesh you will find that both cases fail with "wedge patch front not planar"

Thanks. I checked the mesh again. You are right. there's a point which is not on the front plane.
But the 1.6-ext checkMesh does not show me that infomation.
