BC flux
Hi Foamers,
If i am solving a certain scalar transport equation of a scalar variable "C" in simpleFoam. How to set a "zero Flux" Boundary condition on a patch wall for the "C" Field? help please thanks a lot |
Hello,
do you mean a zero flux BC normal to the boundary face for the scalar quantity C? In that case it simply means you'll have to set dC/dn=0, i.e. zeroGradient. Greetings. |
Hi
Hi ,
yes indeed i need to set that which is normal to the boundary surface is it the same as zeroGradient? because i need only zero flux in the direction normal to the surface, and not in all directions. help please thanks a lot |
Hi,
zeroGradient is exactly what you need: it sets dC/dn to zero (like I said in my previous post), where n is the normal unit vector of the boundary face. For more information please refer to http://www.openfoam.com/docs/user/bo...24-1380005.2.3 . Greetings. |
thanks
thanks a lot.
