Hi All,
I am trying to simulate a roots blower (similar to gear pump) using moving mesh technique (2.5D approach). However, i am not able to proceed in simulation as i am getting the error message 'negative volume" while trying to solve. In display zone motion, i can see that none of the lobes (gears) are overlapping. Could anyone please help me in getting rid of this problem. Thanks.

Hi Kanun,

I'm also working on a similar problem with the roots blower. Appreciate it If you could let me know your experience while solving this.

I'm using OpenFOAM, and need help on this.
