Hi Peter,

I've attached the mesh2d.tar.gz and the sif file.
The DEMS are rather large (344 M).
May be my sif file has some obvious problem that you can spot.

Thanks

Hello Peter,
Thanks for the tip, however, I've tried every value between 10-1 and 10-8 and get the same problem.
I've checked that the x,y coord are identical in the two DEM so I don't know what could be wrong.
Any other ideas?

Thanks

Denis

Hi Peter, Here is how I created the mesh. 1. Create a 2d mesh with gmsh 2. partition the 2d mesh with ElmerGrid 2 2 3. Run the sif file I have added Extrude Coordinate Index = Integer 3 in the Simulation section and can confirm that it extrudes in the 3rd direction. I have also increased the value o...

Hello, I am using the StructureMeshMapper to create a 3d mesh by interpolating between two DEMs. I am getting this error: ERROR:: DetectExtrudedStructure: Zero rounds implies unsuccesfull operation ERROR:: DetectExtrudedStructure: Zero rounds implies unsuccesfull operation StructuredMeshMapper: ----...

Hello, I am using the restart option to continue a run. At the end of the 1st run the time is 6.564E+09 s. Strangely, the time at the first step of the second run is 7.88940000E+006 s. I am not using the Restart Time command to reset the time, only this: Restart File = "$namerunRS".result&...

Hi Peter,

So this mean I can safely remove the solver that ouputs paraview format in my sif file?

Thanks

Denis

Hello Rolbit,

I am having the same problem with post.
Did you ever solve this? Could not so far.

Have you tried the PPA on ubuntu? elmerfem does not seem to be build regularly (last version on the site is 6035, 19 weeks old). Most recent svn is something like 6300.

Thank you

Denis

Hello,

Thanks Matthias and Eelis. I went ahead with the easy CALL FATAL and it works fine for what I need.

Cheers,

Hello,

I'd like to stop a NS simulation when a computed variable falls below a limit, in my case, MeshUpdate 3.
How can I implement this in a .sif file?

Thank you

Hello, I want to create a geometry using ElmerGrid where the bottom boundary of my mesh is a sinusoid. The Mapping mode 5 transforms a line to a sinus but there is no parameter to tell the phase, i.e. I don't want my sinusoidal curve to start at 0,0, there is an offset. How can I do that? Thank you ...
