Saludos,

I have a problem with my simulation Standings and is giving me a negative volume Flow rate

Does anyone know why this happens?

thanks

thanks for reply, the problem was with a goal GG Mass Flow Rate, which stopped the simulation at a very small value of airflow

Muchas gracias y saludos

Hello

I was also searching for answer on this topic. I agree to disagree with Jared.

After testing Jared answer

"into the computational domain = positive"

"out of the computional domain = negative"

I understand now that this is not true! Because either you look for results in computational domain or not, mass flow is always negative. You can test this easily, just extend computational domain and re-run simulation.

I found in SolidWorks knowledge base 100% accurate answer:

S-022094

"Mass entering a

**system**is positive and mass leaving a system is negative."(System, not computational domain!)

Regards,

Ivan

into the computational domain = positive

out of the computional domain = negative
