Hello,
perhaps you can find some answer in chapter 6 of the ElmerSolverManual http://www.nic.funet.fi/pub/sci/physics ... Manual.pdf: Solving eigenvalue problems

Re: Mass Matrix
Could you then try to cast it, i.e., write
instead. Does that help?

Re: No results for Heat Flux
Hello Mat, I guess the no-show of your flux might be connected to the fact that the VTU output is executed as "After Timestep" and the Flux computation as "After All" - make sure that the Flux is computed before the output. What though puzzles me from your output is, that your Fl...

Re: Mass Matrix
Hi, Do you want to have the system matrix written out in ASCII? If this is your goal, a simple Dump system Matrix = filename in the solver section should do it. This was explained in the 6.2 Release Notes http://www.elmerfem.org/forum/viewtopic.php?f=11&t=1443&p=4290&hilit=Matrix+dump#p4...

Re: Interpolation from Elmer results to a new Elmer mesh
Hi, so, the question was: What happens if points do not coincide with the geometry their value is interpolated from? You might get some warning about points not being found in any of the elements. Check the result and choose, whether you are satisfied or not. As I understand, there are some toleranc...

Re: Interpolation from Elmer results to a new Elmer mesh
Hello, provided you have two meshes, mesh A and mesh B. easiest way would be to do a computation on mesh A, so Header Mesh DB "." "A" End and execute the first solver normally on this mesh. Solver 1 Equation = "the first solver" Variable = "VarA" ... End Then ...

Re: can HeatSolver ignore the "Temperature" boundary condition?
Hello, You can basically copy&paste the steady heat transfer solver from chapter 12 of the Solver Manual or try to modify the advection diffusion solver (model #3 in Models Manual). The issue - as I understand it from your previous message - is, that you need convection switched in for temperatu...

Re: Easy compilation in Windows?
Hi, the config.log should be directly in the sub-directory of the module source, where the compilation/configuration failed. For instance, when you spotted errors during compilation of the module fem, then check in fem/config.log My experience (on LINUX/UNIX platforms) with your error message "...

Re: MUMPS workspace too small
I know that this reply is vastly delayed, but I think I insert this piece of information (beside the fact that it has been mentioned in the latest release notes) also here for those who are looking up this thread: The code lines Fabien suggested have been inserted and the corresponding MUMPS paramet...
