Re: Question regarding StructuredMeshMapper

Hi Norbert, By convention, the boundary conditions in your sif file should write: Boundary Condition 1 Target Boundaries = 1 ... End Boundary Condition 2 Target Boundaries = 2 ... End Boundary Condition 3 Target Boundaries = 3 ... End Boundary Condition 4 Target Boundaries = 4 ... End ! cavity roof ...

Re: Question regarding StructuredMeshMapper

Hello,

I can already see one problem:

Variable 1 lx = Real 6512.347200
Variable 1 ly = Real 2022.023200

are not the correct lengths (lx = 6.5013280e+03 and ly = 2.0110040e+03 in the DEM files).

Does it improve results to have the correct values?

Regards,
Olivier

Re: Question regarding StructuredMeshMapper

Dear Nordert,

Can you post your sif and 2d footprint mesh so that I have a look? Did you try to visualize the resulting 3d mesh in paraview instead of ElmerGUI?

Regards,
Olivier

Re: GlaDS--ElmerICE

Hi Arran,

I only see your message now. Did you solve your problem or is it still not working?

Re: GlaDS - how to modify geothermal heat flux?

It is not possible to switch off the cavity (just the channels). I guess you will not be able to do what you want directly with the GlaDS solver but you will have to write your own solver with the appropriate h=h(N) function implemented.

Re: GlaDS - how to modify geothermal heat flux?

Yes, this is m_b from Eq. (12). So in fact, contrary to what I was saying in my previous post, m_b can be directly evaluated as a function of the geothermal heat flux and the frictional heating.

Re: GlaDS - how to modify geothermal heat flux?

Dear Arran, GlaDS doesn't see the geothermal heat flux, but only melt, trough the source term: Hydraulic Potential Volume Source. If you want to include melt from geothermal heat flux (and basal friction and internal deformation) you will have to compute the temperature field and evaluate how much w...

Re: Elmer ice install

Hi Andali, If you want Elmer/Ice to be installed, the installation is exactly the same as for Elmer but with the option -DWITH_ElmerIce:BOOL=TRUE in your installation configuration file. More information on the Elmer/Ice wiki: http://elmerfem.org/elmerice/wiki/doku.php?id=compilation:compilationcmak...

Re: Problems reading DEMs/Internally extruding the mesh

Hi Martim, I found the error (and few smaller ones) in your sif file. The problem is that you have written Variable 1 String "ZbDEM" instead of Variable 1 = String "ZbDEM" (missing "=" sign after variable 1). The Grid2dInterpolator which is looking for "Variable 1 = something" cannot then found any ...

Re: Problems reading DEMs/Internally extruding the mesh

Hi Martim, I can see different errors already: - the DEM should be ordered so that y0 < y1 < ... < yn (see the wiki: http://elmerfem.org/elmerice/wiki/doku.php?id=solvers:grid2dinterpolator) and this is not the case in your file for the y component - Variable 1 lx = Real XX and Variable 1 ly = REal ...
