Hi All,
I have a question.
I make a transient simulation of heating process. I have fan on the bottom of the model. Radial velocity of this fan is -147 rad/s.
Is time step size have influence on the mass flow value on the domain induced by fan?
For the example
Process time is 4,5 h - time step size 1 min
Process time is 4,5 h - time step size 1 second

Best regards
