tangential laplacian
Hi,
I know it is an old post but, I am currently working on the same topic. The boundary condition can be created inheriting from fixedGradient. My idea to obtain the tangential components is applying the laplacian to the field, get its value at the boundary and then substract the second derivative of the normal component. One way to obtain the second derivative is: Code:
. I am unfortunately running into divergence problem in my code. By the way, the tangential components of a vector can be extracted as: Code:
n ^ (n ^ v) Hope that this can help! Hopefully somebody else has a better idea |
tangential BC for laplacian
Hi,
I am also working on it. Is there any update on it? Wondering if there is not already something available... :confused: |
tangential BC for laplacian
Unfortunately, my approach happened to be unstable. If you are working on thin wall boundary condition for MHD, I think the best approach is solving both solid and fluid, i.e. using a conjugated solver
