Elmer Discussion Forum

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...

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...

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 ...

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...

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 "...

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...

Hi,
could you perhaps check in Synaptic, whether you accidentally have hypre installed and hence the library within your paths? The config.log from the fem-directory would help to inquire that.

Dear Sebastian, on a first look I had I think there's something not OK with your mesh or I have issues in understanding what you are after. Three issues I found: 1) the left side boundary for me appears not to be defined all over the height (just load the mesh into ElmerPost and display all lines an...

CSC is looking for a summer trainee to help implementing and develop Elmer modules for effective data I/O in parallel environments, in particular for climate related data stored in the NetCDF format. This includes automated interpolation data and coordinate transformation of coordinates. Time permit...

Hello,
this is just a guess, but you might be in need of either setting the libraries in LD_LIBRARY_PATH or the LDFLAGS ...

Best wishes,
