I am trying to model a natural convection, creating a volume of air around the object i want to simulate.
I didn't have acceptable results, so I'm trying to realize larger volumes or to use alternative shapes for the volume.
But when I do it, and try to simulate i have the following error message that interrupts my simulation:
'Errror 6199
Attempt to evaluate square root of a negative number.
Function sqrt'
how could an enlargement of the geometric dimensions of the volume cause such problem?
