Negative volume
 
Hi,

I am getting a negative volume when I preview my dynamic mesh on fluent. I have tried all the TUI commands to fix it but this does not help.

Can anybody take a look at my mesh for me and see if they can find the error.

Thankyou

Jack

Try using a smaller time step. Just make sure that motion of the mesh does not exceed the size of your mesh elements.
