Re: Building Elmer for Nixpkgs fails

Hi,
do you have QWT library available on your system?

Re: Change of behaviour of SaveScalars solver

Oh, I wasn't aware you had a two year old Elmer version installed.

Re: Change of behaviour of SaveScalars solver

That is odd, since according to the history in github the most recent change in this file is 4 months old and doesn't seem to affect the described behaviour https://github.com/ElmerCSC/elmerfem/co ... calars.F90

Re: Time dependent 3D Maxwell material viscoelastic Earth deformation

Hello, If it helps, please find attached a similar case like the 2D test-case in 3D (runs on my gaming PC with 16 GB RAM and 6 core i5). Picture shows timestep of max. deformation: deformation.0099.jpeg Mind, to first create mesh-file (keeping in mind, that one has to move from kilometres to metres)...

Re: Linear Solver - Different behaviours on different OS

Hi Kevin, I just read that thread - I, personally, would not be that surprised to get different results on different installations (guess also processors?) from Glen's flow law that is regularized with an extremely low value of the critical shear rate. I do not exactly know the setup of your case, b...

Re: Can ModelPDE.F90 handle higher order finite elements ?

I think there is a table expressing the DOF's with regards to the different polynomial degrees in the documentation (https://www.nic.funet.fi/pub/sci/physic ... Manual.pdf) under chapter E1.

Re: getFrictionLoads User Function resulting in segmentation fault error

I pushed a version to elmerice-branch that derives valid Equation from the parent element. Issues might occur on body-body boundaries, but the EISMINT case should now run without the extra body on the boundary.

Thomas

Re: getFrictionLoads User Function resulting in segmentation fault error

Hi, I think the core issue here is that you want to inquire something from an Equation section out of an USF that not directly relates to one (as else it'll be a Solver). In other words: there is no direct relation between USF's and Equation section. In the working example the only reason why it did...

Re: getFrictionLoads User Function resulting in segmentation fault error

Hello, the issue lies within line 184 in USF_GetFrictionHeating.F90 Equation => GetEquation() Which picks the current element and tries to assign an Equation from it. In case the boundary element the USF is executed on has no assigned body (plus an Equation to be applied to it), this will be an unas...

Re: Zero velocities in a finer mesh resolution

Martim, I know this answer comes vastly delayed, but could you try to use the new vectorized Navier Stokes solver with the block preconditioner to avoid running into memory issues? You can find examples on how to deploy it under the latest course pages http://elmerfem.org/elmerice/wiki/doku.php?id=c...
