Re: Elmer+Paraview

Dear armaghantelgerafchi , 1. Paraview is working well as you have put the following code in Simulation section. Simulation ... Post File = case.vtu End 2. You can try changing the boundary conditions that fit the actual physical conditions. The boundary conditions pressure 1, pressure 2 and pressur...

Re: what is the proper Fortran C interface ?

Dear spacedout, Thank you very much for posting a very useful information. This can be very useful when trying to combine CALPHAD database with ElmerSolver through software interface.

Re: Turbulent Flow Simulations with Elmer - A Request

Hi All, With the following updates in the kepsilon solver, Usage of Logical k/epsilon ratio Use KE ratio = Logical True Need for mentioning of transient convergence tolerance Transient Convergence Measure = String "solution" Transient Convergence Tolerance = 5.0e-4 it is good to know that the flow s...

Re: Turbulent Flow Simulations with Elmer - A Request

If the mesh contains prisms or pyramids, at the moment the value of the keyword "Stabilization Method" must be defined to be some other string than "bubbles". If bubble functions were wanted for stabilization purposes, one could try to use for example Stabilization Method = String "p-bubbles" Eleme...

Re: phase change comparison elmer/Comsol

Dear Alex, In general, if there are not any specific advanced requirements of the postprocessing, a simple keyword Post File = filename.vtu in Simulation block would be sufficient to produce a result output in .vtu format. This keyword can be used instead of the Result Output solver (solver 5 in the...

Dear Kevinarden ,
I just noticed that the hskbi.sif file uses the subroutine "bilinear" instead of "hsk_bi " in the myUMATLib.F90 file.


Yours Sincerely,

Re: concentration dependent reaction rate in a diffusion-reaction model

Hi, The variable-dependent equation for reaction rate that you provide is similar to modeling Eq. 1.12 of heat equation in Elmer Models Manual (http://www.nic.funet.fi/pub/sci/physics/elmer/doc/ElmerModelsManual.pdf). The relevant code for the Heat Equation is provided at https://github.com/ElmerCSC...
