New question #135129 on DOLFIN: https://answers.launchpad.net/dolfin/+question/135129
I'm trying to modify the "stiff ODE" demos to use a multi-adaptive solver (I'd like to use this for a more interesting calculation and figured that understanding the demos would be a good way to begin). If I modify the line: ode.parameters["method"] = "dg"; in main.cpp to: ode.parameters["method"] = "mdg"; (and also modify the ODE function to have the correct form for a multi-adaptive solver) then I get an error: Solving test problem number 9. A mixed stiff/nonstiff test problem. Solving ODE over the time interval [0.0, 30] Using multi-adaptive Newton solver. Using discrete tolerance tol = 1e-05. Time-stepping over the time interval [0, 30] terminate called after throwing an instance of 'std::runtime_error' what(): *** Error: No init(..) function for preconditioning uBLASKrylovMatrix Any ideas as to why there's no suitable init function?
