Here is a diff file containing the changes which, modulo a little cleanup or possible bugfixes, I'll be committing to the SVN head this weekend:
http://users.ices.utexas.edu/~roystgnr/femcontext.diff It takes all element-integration-specific member variables in the FEMSystem and parent class, and moves them from there to a new FEMContext and parent class, which among other things should make it possible for a single System to operate simultaneously on multiple Contexts in a multithreaded environment. (Note that the threading code isn't yet there, but these should be all the user API changes necessary to make it work) For other FEMSystem users, the important part of the diff is the ex18 parts at the end, which show the API breakage and the necessary fixes for user-level code: Methods like element_time_derivative() now take a bool+context as arguments, not just the bool. System-wide initialization work still belongs in system::init_data(); context-specific work must be moved to system::init_context(); Because system member variables are now context member variables, a whole lot of things like "element_qrule" are now "c.element_qrule". There's a couple fixes which aren't quite as clean, but which I can't figure out how to improve: Before, we used some nice variables like "fe_velocity" to reference uglier names like "element_fe_var[u_var]"; that's no longer an easy thing to do within a system class that may now have multiple versions of the same object running around in different threads. There's some ugly casts from DiffContext to FEMContext. And there's something I'd like to change, but won't: The "untested();" warning is still in DiffSystem, because I'm still not certain we won't want to make another major change to the API again later. Hopefully this change is the worst of it, though. Anyway, current FEMSystem users might want to take a look before I go breaking your code. --- Roy ------------------------------------------------------------------------------ This SF.net email is sponsored by: SourcForge Community SourceForge wants to tell your story. http://p.sf.net/sfu/sf-spreadtheword _______________________________________________ Libmesh-devel mailing list [email protected] https://lists.sourceforge.net/lists/listinfo/libmesh-devel
