Hello every:

When I start the simulation, always report error messages:

Error: Floating point error: invalid number

and befor that, at the step"initialization"-"compute from", when i select "all zones" it gives a error message:"WARNING: non-positive volumes exist." If there´s somthing wrong in the mesh grid.Please tell me how to solve it.Urgent! Thank's a lot in advance.

It's a problem in your grid.

If you're simulating using the Axi solver, pay attention that the X axis has to me your symmetry axis and that you can't have cells under it.

Regards,

ap

Dear apÄ

Thanks you very much. I moved the whole face in a positive direction and let all grid above zero.it works.

I appreciate your help very much.
