Negative volumetric rate


I got a negative volumetric flow rate in my CFD modelling design. This is an unexpected result, can I get some help with this.

Hi Jordan, is it possible that you also provide the link to the project?

Best regards,

Hi Fillia,

here is the link to the simulation.

I ran a different simulation where I switched the location of the velocity in and out in my model and this produced a positive volumetric flowrate. This is the second simulation run in this model.

Kind regards,
