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 = Stri...

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...

Re: coupled fluid flow and heat simulation

Looks like it works with a smaller timestep. In context of ElmerSolver,in order to attain convergence in the numerical solution, especially when coupling navier-stokes equations with heat equation, the timestep size can be designed an order smaller than the length scale size . E.g. if the length of...
