Re: Get "solution trivially zero" when I run with MPI

Hi Romuald

Probably the Metis routines could not operate with the orphan nodes as they do not belong to the connectivity graph.

You could try using

Code: Select all

-metiskway 4 -partdual -removeunused
Dual graph may give smoother domain interfaces.

Re: how to save memory on BCs

Hi

There may be a "NormalSolver" that only solves the Normal field at the BCs.

Re: Get "solution trivially zero" when I run with MPI

Hi

Probably your "autoclean" renumbers the BC indexes so that you don't really apply BCs at all. Or do you really have >1000 BCs?

Seems unintentional. FIxed in devel. Thanx for reporting. -Peter

Re: Time step sub-cycling

H "Active Solvers" is unfortunately not as elegant as you imagine. It just lists all active solvers and they are performed in the order or their index (if not "exec solver" defined otherwise). There is a keyword "Timestep Scale" that may be used to cheat on the timestep of individual solvers. There ...

Re: Inductance Extraction (MagDyn2D, MagDynPost, Circuits & Dynamics)

Since two minutes there is a keyword for CalcFields solver:

Separate Magnetic Field = Logical True

This will enable to print out the parts separately. This could be a default but I worry that there are some uses of this out there. This should be backward compatible.

Re: Reading gmsh mesh with elmer (ElmerGrid/Elmer GUI)

Well, the files are now identical. Ideally the common part would be a library. However, I didn't change the cmake part so if you change stuff in ElmerGrid you need to run this: https://github.com/ElmerCSC/elmerfem/blob/devel/ElmerGUI/Application/plugins/grid2gui.sh Symlinks would have done the same ...

Re: Order of Solver Execution for Coupled Solvers

Hi

In ElmerGUI the numbering of Solvers (aka modules) may be determined by the priority. Give a higher priority to the Solver you want to solve first (bigger number).

Re: Inductance Extraction (MagDyn2D, MagDynPost, Circuits & Dynamics)

Hi SaveScalars is agnostic to physics. It just saves stuff that is provided by other solvers. We have a pretty dirty way of communicating values to SaveScalars: We add strings with prefix "res:" to the Model % Simulation list. If you want to understand where the Energy is being computed look "Energy...
