hi colleagues.

I need some help with mass inlet, because I have a problem about input flow. My flow is 0.005 and consistently throws me an error.
Is it possible to work with such low flow rates, because when you put the alarm again one mistake. How to define?

What is your problem exactly?!

I have a small amount of water vapor that evaporates into a large amount of air. How to simulate. whether to put the vapor mass-flow inlet and if so how to define it.

Flow is known to me from measurement and is 0.005

please explain your geometry, boundary conditions, aim of simulation etc so that we can help. What is 0.005? is it mass flow rate? mass fraction of water vapor? or...?

I have a vaporizer for milk rectangular profile, one inside the other. At the entrance are the following: Preasure inlet, temperature 30C, speed 0.7 m / s 70% humidity. Other walls are at 85C.

The upper edge of the inner profile of the milk temperature 100C. Simulates the process of cooling of milk, which brings the temp 100C in an air channel. to determine how much moisture flux and indulging in the airflow.

I am the first to put my surface edges with milk inlet preasure but I think it is better to work with mass-flow inlet.

Oh! That is not quite simple for me to understand. Any way, now what part is difficult to handle?

p.s.: Is it possible to upload an image of geometry plus B.C.?

It does not matter, I finished
sorry I'm late with the answer
