Re: "HeatSolveVec" "HeatSolver" simulation time speed up?

Hi, Thanks to both of you for your support. It appears to me that Save Coordinates crashes when it is used along with Discontinuous Galerkin. I have uploaded a simple example here: http://www.elmerfem.org/forum/viewtopic.php?t=7698 The problem is not caused by the keyword 'Real' I have to experiment...

Re: Save Coordinates Crashes with (Discontinuous Galerkin) Heat Gap

Hi Rich,

the purpose of the 'Discontinuous Galerkin' line is to implement a heat gap between the two bodies:

If one replaces the line 'Discontinuous Galerkin' with 'Discontinuous Bodies' in solver 1, then the heat gap is ignored by the solver:

Save Coordinates Crashes with (Discontinuous Galerkin) Heat Gap

Hello,

attached is a minimal example where 'Save Coordinates' crashes when the HeatGap between 2 bodies is active.

"HeatSolveVec" "HeatSolver" simulation time speed up?

Hello, given the mesh and given the computer (i7-9850H @ 2.6 GHz), does anyone have some hints to speed up a 3D Heat simulation? Are there any parameters in the Solver 1 section that can be modified to improve the simulation time? Here are the mesh information: mesh_information.png The simulation ti...

Re: ElmerGUI: wrong solver specific option shown

Hi Rich,

thanks for your reply.
I noticed too that sometimes the menu are crossed and sometimes they are not, but I couldn't find a rule.

Best regards,
Matteo

Re: Save Scalars: mixed up result file in parallel run - SOLVED

Hello,

from ElmerModelsManual:

Code: Select all

Save Coordinates(n,DIM)
So it should be:

Code: Select all

Save Coordinates(2,3) = x1 y1 z1 x2 y2 z2
(notice that 2 and 3 are swapped)

Re: Scalar potential BC, WhitneyAVHarmonicSolver

Dear Ivanov, I'm learning from your post how to solve similar problems. I think a problem your example might have is that the mesh is too coarse on the surface of you conductor. If I'm not wrong, the dimensions of your bodies are: conductor radius: 1cm Air radius: 10cm Length: 40cm The length of the...

Re: SaveLine: simulation time in output file

Hi, I was indeed interested in including the time in the SaveLine output file. I was expecting the solver to stamp the same time value for every point along the polyline, for each time step. The time of each step would then be available in the SaveLine output file, although repeated n times for each...
