Re: Plot variables

Hi Matthias, I ask me for a week the same question. I found a solution that works to display the value in the solver log window. Concerning the User variables that are defined in the sif or Elmer variables: I wrote some printf commands in a free text input (e.g. in Result Ouptut Solver) the two last...

Re: Heat Source unit in w/m^2

Hello, sorry for responding late! I notice a small typing error there. In the unit conversion it should be 2.500e-3 m2 instead of 2500e-3 m2. The results are overwise correct! heat flux= 100W/m / 0.181m²/1000kg/m³=0.55W/kg heat flux= 13.5W/m / 2500E-3m²/8900kg/m³=0.606W/kg if you calculate the heat ...

Re: How to get in-between output results of solver ?

Hi, concerning a missing free text input in a solver, you can edit manualy the .xml solver file with a text file editor (e.g.Notepad++, Windows Notepad...) Then you only have to add some code lines in the section where you want to get a free text input (e.g. Equation, Bodyforce, Initial condition, B...

Re: Creating a mesh file

Hello jin, please avoid asking similar questions in several topics. You will maybe get more answers but this is not the better way to help the community! I propose you a method with Gmsh in your first topic below: What are the steps to create a mesh file for Elmer to solve? http://www.elmerfem.org/f...

Re: guidelines for creating IGES geometry

Hello Jin, following your questions, I propose a way I would use in this case. (other ways do exist) 1. How can I create mash in freeCAD? design only the geometry in Freecad and export it in step or iges format 2. How do I export mash from freeCAD and prepare for meshes for Elmer? You can use FreeCA...

Re: Creating a mesh file for Elmer

Hello Jin, on my side I use Gmsh to generate my geometry file (.geo format) and the mesh file (.msh) The download link for Windows is there: http://geuz.org/gmsh/ I started 2 weeks ago to learn how to use this tool, and I am now able to realise mesh files of quite advanced geometries. FreeCad is may...

Re: Tutorial 21 Actuator driven with electrostatic currents

Thanks Peter for your explanation, I understand now better the difference between the two methods. It means that for this tutorial, it is not a matter to use the calculated Joule Heating as Heat source because there is only one material and therefore no discontinuity. I have also found the reason fo...

Re: Tutorial 21 Actuator driven with electrostatic currents

I don't manage to answer the two questions posted above. Could someone explain me the role of the tick-box "Joule Heating" in comparison with the variable transfer "Equals Joule Heating" ? Should I use both or ticking the box is enough? In ".\Elmer6.2\tests\current_heat_control" the example doesn't ...

Tutorial 21 Actuator driven with electrostatic currents

Hello all, the questions are right down at the bottom but I need first to give some explanations. I am learning how to use Elmer GUI. I try to reproduce the tutorial 21 Thermal actuator driven with electrostatic currents in Elmer GUI. - In this prospect I make sure that the Static Current Conduction...

Re: Static current conduction

Hi Markus, I don't know if you challenge to solve your Problem. I am also trying to simulate the heating-up of a copper conductor. I discover Elmer GUI few days ago and I am really impressed, it is quite nice to use even if I don't know the most functions! After some researches, I found how it is po...
