Hello Fluent users: I have been trying to solve a case study in fluent involving moving walls but was not successful. Every time when i try to repeat the examples in the manual, i get the following error message after a few iterations.
"Negative cell volume detected" Any thoughts to overcome this would be very helpful. |

Hi guy,
I've got exactly the same problem than you. In fact you need to input a dynamic mesh. I wonder if we don't need any grid interfaces in more, I will let you know if I succeed. |
