Problem with boundary conditions

giack · August 1, 2013, 06:20

Hi to all,
I have a simple question about how Bcs are treated by tecplot. When I load the simulation Tecplot doesn't load the Bcs and the value in the last domain cells is wrong. Someone knows the reason of this strange behaviour?

Thanks to all

What is the file type you're reading into Tecplot? And what are you outputting from your CFD solver?

Generally, Tecplot will have zones where each zone should correspond to a boundary. Depending on how your CFD model was set up, it will be called something different.

Hi Giack,

Do you mean the last cells close to boundaries (like walls) do not behave the way like you defined your BCs? If so, you can try to select Zone Style -> Contour -> Contour Type -> Primary value. There might be linear interpolation if use Flood in contour type.

Hope that helps.
