Re: how to handle multiple save scalar?, locate, line break

Thanks for answering. quick answer attempts: 1. I don't know 1.1 did you try in ParaView? You can select a node or a cell, display Temperature etc, ... Are there Paraview or gmsh for postprocessing python tool chain examples, would be the question. 2. see here (Result of a quick forum search for &qu...

how to handle multiple save scalar?, locate, line break

Hi, got some 3, 4 problems with save scalar interface I could not learn from the docs and put them here in one post - for reasons of ease. Sif file, heat conduction, attached. 1. (locate minimal temperature at boundary) Hopefully succeeded in gaining a value, but need to obtain the coordinates then....

Re: Conversion back to msh; ElmerGrid 3 4 .ep seg fault

Hi Matthias, hi all, -just found it by myself in the manual and came to report it. Thanks in any case. And as well for commenting, which is quite important for me. (-It is explained in Tutorial 7 of gmsh to use "background meshes" for "element size setting". However there is no e...

Conversion back to msh; ElmerGrid 3 4 .ep seg fault

Hi, in my current project I want to build the mesh from the output of the gradient. Got vtu, ep, dat and ep.el as result and need to convert flux-valued .msh format. Question: 1) Is that a sensible way to go? Which source should one choose better? 2) Why is it seg faulting? Tia /elmermesh1/angle$ El...

Re: film set to zero alters the correct result, bug?

Hi, It is a problem of conflicting BCs and order of BCs. If you have no conflict there is no problem. I would be pretty confident that the HeatSolver of Elmer for basic analysis is correct. There has not been essential changes to it in years and many people have applied critical tests to it over th...

Re: How to increase accuracy?

Hi Michal, you know what I found out? Compare this two figures from national iso-standards: I sat hours doubting what was saying mine, see body 3. For big luck I found yours. What without you?? Thank you. For that standardization bodies charge thousands of Euros annually, that nobody notices their b...

Re: film set to zero alters the correct result, bug?

Hi Peter, in this case there are no adjacent boundaries!? See geo and screenshot:the boundary lines are spacial separated. Maybe you confound this case with a parallel case, which comes after and where Dirichlet Temperatur conditions are adjacent: see picture in this post: http://www.elmerfem.org/fo...

Re: Convergence of heat conduction equation with Joule Heating

Hi Anil, to my experience, you should not have convergence problems for a large range of configurations. Did you have difficulties so far? Matthias Hi Matthias and Anil, I believe that is true, in the sense that result gets closer each iteration to a certain value. But it gets somewhat doubtful if ...

Re: film set to zero alters the correct result, bug?

Hi Peter, this is your comment? ;) Ok? Yes it is true, I changed it, when I saw converging (over iterations) without any drift in the output and as I had bigger aberrance through over mesh size divergence and no time. Well I keep it in mind when I get out of validation space. Thanks for the hint and...

Re: How to increase accuracy?

But I have two practical problems, that make my investigation little annoying, if someone could help I would be very thankful. 1) I use Elmer in Windows. When I load project file in Elmer, it overwrites the .sif file and I have to assign it again... Is there any verified method to smoothly run comp...
