setRegularizedHeatFluxBoundary

[Jijo]

Dear OpenLB community,

I have tried to use the (setRegularizedHeatFluxBoundary) as a Neumann boundary condition for a heat flux but whenever I set the heat flux to certain value and check Paraview it does not corresponds to the similar magnitude. Code:

T heatFlux[2];
heatFlux[0] = 0.0;
heatFlux[1] = converter.getLatticeHeatFlux(Certain Value);

setRegularizedHeatFluxBoundary<T,TDESCRIPTOR>(ADlattice, Tomega, superGeometry, 5, heatFlux);

and I used (SuperLatticePhysHeatFlux2D) to view the heat flux. Any help on such issue?

Best regards,

Dear Jijo,

thank you for your post.

Please have a look at the examples/ in OpenLB which showcase the usage of setRegularizedHeatFluxBoundary for straight walls (curved walls with a heatflux boundary need specific treatment, which is currently still under development).

In addition, the output functor you use might produce a magnitude value in Paraview which can differ if the shape of the boundary is curved.
