Elmer Discussion Forum

Hi, during my thesis i wrote a solver for simulating the strongly coupled heat and moisture transfer in wood. You can download the actual version v1.0.0 at https://savannah.nongnu.org/projects/xtwoodsim/ Follow the Link "Sourcecode" --> Use Git to get the last snapshot. The case is tested ...

Hi Peter, posting an article at the wiki would be cool. I'll ask Sampo Sillanpää for the login with a hint to this forum entry. We could try to organize some subdirectory in the source files for contributed stuff Do you mean a subdir at sourceforge or how would it work? Would you prefer to have it i...

Hi Elmer Team, during my thesis i wrote some code for strongly coupled solvers for transport phenomena in wood. I'd like to make them available under GPL and link with other institutions to improve and advance the models, similar to the Elmer/Ice Project. Is it possible to publish as usergroup at th...

Hi, you can give the Youngs Modulus as a 6x6 Matrix. Youngs modulus(6,6) = 2500 -33 -600 0 0 0 \ -33 61.6 -27 0 0 0 \ -600 -27 1430 0 0 0 \ 0 0 0 1590 0 0 \ 0 0 0 0 27000 0 \ 0 0 0 0 0 1290 I'm not sure if you have to give the stiffness or compliance matrix. Greeting, Uwe

Hi Elmer Team, when coding a solver for a coupled problem i put a statement like Variable = STRING Field[var1:1 var2:1] Variable DOFS = 2 Procedure = "MyLibrary/mySolve" "mySolve" in the sif file. When doing the element matrix assembly the order of the variable in the solution ve...

Hi Peter,

that's right. For direct solver it's an advantage.

Thanks a lot for your help.

Uwe

Thanks, seems to be easier than expected. For solving it staggered i could simply call the DEFAULTSOLVE() in between and iterate with the new Solution. If i read the code right you ordered the solution vector pairwise (Node1_Temp, Node1_Current, Node2_Temp, Node2_Current, ...). Is there a speed adva...

Dear Elmer Team, getting deeper into Elmer is quite interesting. Thanks for this nice piece of software. I solved some weak coupling problems for my thesis being quite happy to be able to use open source software :-) At the moment i am working on a strongly coupled field problem, coupling temperatur...

Hey Jin, also see the documentations at http://www.csc.fi/english/pages/elmer/documentation The ElmerGuiManual.pdf has some informations about importing meshes. Chapter 6.2 of ElmerOverview.pdf lists some ideas for pre-processing. The ElmerTutorials comes with some files where you can learn to impor...

Hi i used the pre-installed elmer version of CAELinux 2010 which is a ubuntu 10.4 derivative. The elmer version was 5.5. I used the elmerf90 command to compile, which used the gnu compilers. After deleting this elmer version and all related packages and installing the 6.0 version of elmer with hypre...
