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 ...

Re: Problems reading DEMs/Internally extruding the mesh

Dear Martim,

If you want me to test your example, I need the mesh to do it. Just the two DEMs and the sif is not enough.

Re: How to use Elmer

Hi,

We don't use the GUI in the Elmer/Ice course doesn't mean you cannot use for other purpose!

Re: Updating side boundaries with two free surfaces

Hi Laura, First, I would suggest to use the StructuredMeshMapper solver instead of the old MeshUpdate one. See for an example the Tests GL_MISMIP in [ELMER_TRUNK]/elmerice/Tests/GL_MISMIP. Second, I think the only conditions for the right and left boundaries are "Velocity 1 = Real 0.0" and "Mesh Upd...

Re: Problems with executing Elmer/Ice examples

Are you executing the commands in the directory that contains the files testglacier.geo and Stokes_diagnostic.sif, i.e. in the directory TestGlacier? If not, you should first move in this directory (e.g. cd home/home/elmerfem-release-8.3/elmerice/examples/TestGlacier/) and then execute the different...
