Hi All,

I am writing a UDF to reproduce standard k-omega model using UDS and etc.

Does anybody know what is the wall boundary condition for specific dissipation(omega) in LRN(Low Reynolds number) approach?

I am avoiding HRN(High reynolds number) ie, Wall functions.
In the theory guid it is said that omega value at the wall bc is as shown in the attachment.

But my solution diverges as soon as I impose this BC.

Any help is appreciated.

Thanks,
Ali
