Hi,
I am using directionMixed BC and want to know the within used tangent vectors. To precise my question: Let's split v into the face normal component and into two tangential components like v = v_n *n + v_t1 * t1 + v_t2 *t2 When I am using directionMixed like this: refValue uniform (0 0 1); refGradient uniform (2 3 0); valueFraction uniform (0 0 0 0 0 1); I have set the boundary conditions (hopefully) like: v_n=1; \partial_n v_t1=2; \partial_n v_t2=3; To get the face normal vector n I am using: mesh.Sf().boundaryField([b_outlet]/mesh.magSf().boundaryField([b_outlet]; How can I get the tangential vectors t1 and t2 ? Maybe someone has an useful hint, Martin. |
