Most of our users with relatively straightforward problems to solve usually do so by picking a libMesh-based framework (i.e. MOOSE or GRINS, though I also have a simple little framework that I give out for use on simple physics) and writing a new kernel to add their physics to it. Most of our users who need more fine-grained control (or who started using the library before MOOSE was open sourced and GRINS matured) start with one or another of our examples and modify it. > but I still can't get my own problem up and running. Your best source for help here is probably the libmesh-users mailing list. I try to be as helpful as possible, but if I'm stuck in meetings (as I was Wednesday) or out of town (as I am until tomorrow) then I'm pretty slow on the draw, and there are other users and developers who are good at taking up the slack. > If someone were brand new, perhaps so new they didn't know the right > questions to ask, where would you first send them to learn this > library? If you're doing things properly, the first step in any simulation is a "design document", describing exactly what you're trying to model and what the mathematical formulation of the model is. If you don't have something like that already, you should - aside from design philosophy, it'll be the core of your thesis and papers, and better written sooner than later. If you *do* have something like that already, then I'd say chop out the bare essentials (PDEs, boundary conditions, etc) and post a link to libmesh-users asking how best to get started. > I really appreciate the help! Sorry about the delay. I'll Cc: this to libmesh-users so others there get a heads up and so you can see the email address; IIRC you'll need to subscribe at https://sourceforge.net/p/libmesh/mailman/libmesh-users/ before the mailman software will allow you to post yourself. --- Roy ------------------------------------------------------------------------------ _______________________________________________ Libmesh-users mailing list Libmesh-users@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/libmesh-users
