Hi, thanks again.


What would you suggest to make continuity converge? I get floating point error when I use the UDF, however if a constant Pressure is set (in the pressure outlet), FLUENT doesn't seem to have any trouble dealing with it.

 I'm even considering making different steady simulations, since the transient seems to have that much trouble. But it really should be possible to make the transient case, since giving the values from the UDF as constant pressure it works just fine.

Edit: Using density solver seems to be helping

Edit: Still not able to run a proper set up, I think the problem could be the Helium not being able to change shape during the fligt. Since it changes density, using density solver reflects anormally high temperature in the film.

Best Regards,
