New question #102995 on DOLFIN: https://answers.launchpad.net/dolfin/+question/102995
I am trying to mark a curved boundary which is a PHYSICAL boundary, but it seems dolfin does not take the boundary into account. my curved boundary is just a semi-circle with a radius 0.5 and the center locates at (0, 0) What I do is below, class Cboundary(SubDomain): def inside(self,x,on_boundary): return on_boundary and (abs(x[0]*x[0]+x[1]*x[1]-0.25)<tol) bc = DirichletBC(W.sub(0), noslip, Cboundary(), 'pointwise') Changing the value of tol is not useful as I tried. -- You received this question notification because you are a member of DOLFIN Team, which is an answer contact for DOLFIN. _______________________________________________ Mailing list: https://launchpad.net/~dolfin Post to : dolfin@lists.launchpad.net Unsubscribe : https://launchpad.net/~dolfin More help : https://help.launchpad.net/ListHelp
