Elmer Webinar series? Call for presentations!

Hi All, The past year has been challenging. We have been thinking about how to best adapt to the still ranging pandemic. We came up with the idea to organize some webinar series where people around the world could present how they use Elmer in their work. The content could be mostly about use of Elm...

Re: Nodes grouped with regard to geometry and boundaries

Hi I suggest you use "Calculate Loads = True" and then appropriate "boundary sum" operator in SaveScalars module. You may need to do this component-wise to "Flow Solution Load i", i=1,2,3. This will get you the most accurate force estimation possible that includes also ...

Re: About how-to set surface tension in Level Set Method

The "ELMERSOLVER_STARTINFO" is a bare file. You probably introduced the .txt suffix yourself when copying the file into Windows.

Re: VariableAddVector - elmental variable

Hi I checked this and it seems that elemental variables get correctly treated. IP variables had some issues. There is now a version that can deal also with those once you say "Output IP Variables = Logical True". This is in devel branch. I don't yet know whether to make it a default. -Peter

Re: About how-to set surface tension in Level Set Method

Hi Tutorials exist only for a small fraction of all the capabilities. Levelset has not really been in the focus lately. Probably the only test case with surface tension is the test case "LevelsetFallingDrop". Additionally I would refer to the Models Manual. There are also some other levels...

Re: Tutorial 16 Flow through a hole (in MEMS microperforation)

Ok, I read some more of the discussion. Do I read correctly that you think Re is small enough to stay in linear regime whereas Ma may not be small enough to allow compressiblity to be neglected? One possibility is to use the linearized time-harmonic Navier-Stokes equation. If you can assume linear d...

Re: Tutorial 16 Flow through a hole (in MEMS microperforation)

Hi What is the Reynolds number for your problem? Was the failing to converge the reason for introducing turbulence? I could see that there is some turbulence around the corners. However, these old results of Veijola certainly were computed without turbulence as the Reynolds number was deemed to be r...
