Others will hopefully know more than me, but there are 3D infinite elements, both geometric http://libmesh.github.io/doxygen/classlibMesh_1_1InfCell.html and finite elements http://libmesh.github.io/doxygen/classlibMesh_1_1InfFE.html I have no idea how they work. The person that wrote those has not been active in libMesh development for a long while. I'm hopeful some of the other developers have more knowledge. I can at least point you to an example where they're used (wave equation): http://libmesh.github.io/examples/miscellaneous_ex1.html ------------------------------------------------------------------------------ One dashboard for servers and applications across Physical-Virtual-Cloud Widest out-of-the-box monitoring support with 50+ applications Performance metrics, stats and reports that give you Actionable Insights Deep dive visibility with transaction tracing using APM Insight. http://ad.doubleclick.net/ddm/clk/290420510;117567292;y _______________________________________________ Libmesh-users mailing list [email protected] https://lists.sourceforge.net/lists/listinfo/libmesh-users
