New question #159021 on DOLFIN: https://answers.launchpad.net/dolfin/+question/159021
I would like to assign an initial guess to two solution variables in the following way, given two functions u0 and v0: V = FunctionSpace(mesh,"Lagrange",1) W = MixedFunctionSpace([V,V]) phi,psi = TestFunctions(W) dU = TrialFunctions(W) U = Function(W) du,dv = split(dU) u,v = split(U) #Here is where I would like to assign initial values u0 and v0 for my non-linear problem u.assign(u0) v.assign(v0) u0 and v0 are already defined as functions on the appropriate function space. When I use this particular syntax, I receive an error message stating that indexed objects don't have an assign method. Fair enough, but how do I bypass this so that I can assign an initial guess. This problem cannot converge from a zero starting solution. -- 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
