Re: interpolation along polyline in SaveData

You are right, isoSurfaceSolver doesn't work with coordinate variable. I see your point on having dx and dy scaled very differently. This solution with saveGridData work well for this case where I want an interpolation along x,y or z, but for lines not along the axis it will not work. Maybe I will a...

Re: interpolation along polyline in SaveData

Hi Peter Yes I have already used the SaveGridData to save a grid on the boundary (with a mask on the boundary), so I can get my interpolation for the two lines I want in the x and y direction. But I can not see how I with the SaveGridData can get only 1D extraction? Can I put a mask on a line? The I...

interpolation along polyline in SaveData

Hi all

I would like to get the interpolated values along a polyline, but I can't see that this feature allready exist in the SaveData module. How dificult would it be to modify the SaveData for this feature, or does it almost exist in another module? The SaveGridData seems very close.

Regards
Rasmus

open the forum to Tapatalk

Hi All

Is it possible to open the forum for Tapatalk. I use this small app on my mobile to follow many other fora on a daily basis.

As far as I can see it should be fairly straight forward to open this forum for acces with tapatalk

Re: Internal extrusion of boundary of 3D solution

I have now continued a bit and think I am on the right track... I save the 2d boundary that I want to extrude also from my mesh generation (salome), so I get both the full 3d and the 2d mesh of the part I want to continue with. I then use a combination of reloaddata and InterpolateMeshToMesh to load...

Re: Installing, Compiling & Running ElmerNonGUI in Ubuntu 14.04

Also a note that the

Code: Select all

 make -j 8
is for compiling on a system with 8 or more cores, so the number after -j should preferably be equil to or less than the numbers of cores on the system that you compile on.

Re: Some compilation issues for Elmer nonGUI in Ubuntu 14.04

It compiles fine for me on Ubuntu 14.04 I use this compile script: #!/bin/sh -f # Compile Elmer modules and install it # export ELMER_HOME=/opt/Elmer # replace these with your compilers: export CC=gcc export CXX=g++ export FC=gfortran export F77=gfortran modules="matc umfpack mathlibs elmergrid...

Internal extrusion of boundary of 3D solution

Hi all I would like to use the internal extrusion on a boundary from an earlier 3d solution, and use the velocity field on that boundary of the previous solution as the boundary condition on the new extruded mesh. Imagine a flow solution of a pipe in 3D. I would then like to either save only the 2D ...

Re: Chemical Reaction

Hi Peter

I would be interested in your earlier efforts to make the CRE module for Elmer. If you can dig it out I will have a look at it and let you know if I can continue/finish the development for such a module.

Best regards

Re: iterative != direct solution for diffusive flux

Just had an idea to the difference... The "Coordinate Scaling" in the Simulation section. If I remove this part I get the same solution, so it seems that some issue exist with the implementation of the "Coordinate Scaling" with the iterative solvers... Some further testing reveal...
