Re: Pyramid element with ElmerGrid

sato , can you try exporting linear elements form Salome and then calling ElmerGrid 2 2 -increase ............. ElmerGrid manual says that the option -increase : increase element order from linear to quadratic The original SalomeToElmer script cannot export quadratic elements. If you can figure it ...

Re: Newbie question: Paraview not working

1) No, ElmerPost is not needed for ParaView.
In *.sif file, if you have this line
Exec Solver = never
inside ResultOutput solver, then remove it or comment out.

2) https://www.paraview.org/

SaveMaterials for vectors and tensors

Hi When exporting Material property 1) As a scalar it works: Material 1 TRRR = Real 1 End Solver 1 Procedure = File "SaveData" "SaveMaterials" Parameter 1 = String "TRRR" End 2) As a vector it does not work - exported variable "TRRR" is absolute 0: Material 1 TRRR(3) = Real 1 2 3 End Solver 1 Proced...

Re: Discontinuous Galerkin for convective heat transfer problems

Although it is not Discontinuous Galerkin solution, your solution helped me to find a bug in my viscosity value. I was using kinematic instead of dynamic. Thanks!

Discontinuous Galerkin for convective heat transfer problems

Hi,

I am trying DG for simple convective heat transfer problem - curved pipe, 2D

EOF-Library - Introducing Elmer FEM and OpenFOAM coupler

Hi! With this post I want to introduce EOF-Library project and bring Elmer and OpenFOAM communities a bit closer. To my knowledge there is no other proprietary simulation tool that can couple FVM and FEM more efficiently in terms of performance as this tool so lets use this time advantage in our fav...

Re: Computing convective heat loss without air

If you know heat transfer coefficient [W/(m2*K)] then your problem reduces to simple heat conduction. This is easy-peasy for Elmer.

Tests that are solving heat equation with "heat transfer coefficient" shown in picture

Re: Synchronizing target variables and fields of EOF-Library

Hi Anil,

1) Yes, Joule heating in Elmer is in W/m3.
2) Not sure whether you need to use alphaEff or nu()/Pr. Thinking about kappa (thermal conductivity) I think it is typically measured for non-moving fluids and gasses. To be on safe side, better ask someone with CFD knowledge :)
