then try inletOutlet

type inletOutlet;
inletValue uniform 0;
value uniform 0;

hi.
with inletoutlet i achieve convergence at 313 but when i view my domain.. then complete blue colour ie zero velocity..

Hi Nima,

I'm using OF2.2.2 and am solving a laminar problem using modified buoyantBoussinesqSimpleFoam. blockMesh compiles well. But when I run it I get this error. Its the same as what Izna had. I've double checked the boundary conditions and the geometry. They seem to be fine. I do not know why this error persists

Code:

I have also attached my fvSolutions file and blockMeshDict file. The fields that I have are p p_rgh T U and alphat. I have removed the other fields as I have switched off turbulence. Is that ok?

Thanks in advance.blockMeshDict.txt

Hi,

Judging by the error that has appeared I think its a problem in my fvSolutions file. Am I right? Also, since I've switched off turbulence I needn't include the discretization schemes for k, epsilon, omega and nut, right? Is that what is causing the error?

Update: I just tried running another solver with the same boundary condition. and I get the exact same error. Is it a generic one? I'm not able to find out what it is from the error that I get. Any help will be really helpful, 'cos I'm lost at this point.

Thanks.
