All, every once in a while we had questions about problems in which there were different equations on different parts of the domain (e.g. coupling solid mechanics with the flow of a fluid around the body), or in which the equation only held on parts of the domain (e.g. when modeling bodies with voids).
I've long had this idea how to do this, and I've now also written a little tutorial program that shows how to use this technique (and fixed all the bugs this uncovered): step-46. This program shows how to couple Stokes flow in one part of the domain with the elastic deformation of a solid in the remainder of the domain. Take a look here if you're interested: http://www.dealii.org/developer/doxygen/deal.II/step_46.html As usual, feedback is very welcome! Best Wolfgang PS: Thanks go to Joshua White and Thomas Wick for useful comments. Joshua also wrote the initial implementation of FE_Nothing. ------------------------------------------------------------------------- Wolfgang Bangerth email: [email protected] www: http://www.math.tamu.edu/~bangerth/ _______________________________________________ dealii mailing list http://poisson.dealii.org/mailman/listinfo/dealii
