Hello,
Yes it helps thank you!
Though many confusing points
I think I am ok on a IBM simulation which allow fluids and solids.
Also that i don’t do a “negative of the devices” cut from the air flow box otherwise i can’t specify iron material /vs the flow box.
But
if i don’t put a boundary, the boundary dot stays red and the simulation tells :
- Temperature field does not have a reference level because there is no fixed temperature boundary condition. Please provide at least one boundary condition where the temperature is fixed or consider using natural convection inlet/outlet boundary condition for natural convection cases.
If i put the boundary with the flow box and natural convection, some faces are not recognized …
For the temperature : I set initial conditions 20 degres + 2 subdomains for the two irons pieces: 20 and 80 degres.
This set up is confusing because anyway the system says needing the boundary for ambient temperatures so it is redondant.
Maybe not needed:
-
The IBM propose a cartesian shape for the flow box but maybe it is not needed as there is a flow box.
-
Also the option for passive scalar talked about in the tutorial you kindly sent me doesn’t appear in my initial conditions.
-
As well the contacts set up might be not needed, as they are supposed to be done automatically.
The set up as it is now doesnt go further than 5%, tried 3 times. Couple for few hours with no progress…![]()
