New question #152914 on DOLFIN: https://answers.launchpad.net/dolfin/+question/152914
Hi, I want to solve a PDE on a one-dimensional domain. The equation involves a first derivative. How do I express this in 1D? Here is (basically) my equation: dT/dx + d^2T/dx^2 = 0 and weak form a = (grad(T)*v - inner(grad(T), grad(v)))*dx with testfunction v and trialfunction T. When I use grad(T), I get a "shape mismatch in sum" error. The mesh is Interval(100, 0, 10) -- 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 : [email protected] Unsubscribe : https://launchpad.net/~dolfin More help : https://help.launchpad.net/ListHelp
