Re: (p)arpack compilation error

Hi, I do not have a lot of answers. The HUTI_D_DG is a function defined in the linear algebra package HUTITER, which is under elmerfem/fhutiter/src/huti_sfe.F90. The MPI_ALLREDUCE error beats me - the only difference I can spot to other calls to the same function in other routines is, that the send ...

Re: Mumps on Taito

Hi Rupert,
This forum is not scanned for requests concerning CSC's computing platforms, instead I would ask you to send a request to CSC's servicedesk instead. Once you do, I will try to fix things. I guess you need the FISOC branch installed there.

Cheers,

Thomas

Re: Help to apply shear force at boundary

Hi Liz, somehow I missed your reply from March 4th, sorry. If you really have an apparatus where two parallel plates to which the ice is attached are pushed with a shear stress and not vertically displaced (I still wonder how you can achieve that without cracking the ice), I would deploy the FreeSur...

Re: Elmer compilation problem on Cray cluster

Hello, I do not know if this is of particular help in your case, but here is the compilation script for GNU environment on our Cray XC40 attached at the end of this message I think the essential two lines are CRAY_ADD_RPATH=yes export CRAYPE_LINK_TYPE=dynamic Naturally, you need to change a few path...

Re: The status of ElmerIce tests

Hi Rupert,
as the freesurf_maxd serial test runs through, I presume there is a problem with parallel set up. Could you send me output to see where it fails (is it the norm?)?

Damage test never worked for me and the Thickness problem is - as I reckon - being worked over.

Regards,

Thomas

Re: Help to apply shear force at boundary

Hi Liz, tangential forces can be applied with the keywords Pressure {1,2,3} for directional applied surface stresses (force/unit-area) or External Pressure for normal external pressure (I know, the naming is unfortunate, but this is something from old Elmer history). In your particular case I'd spli...

Re: can elmerice compute ice velocity

Dear Saisai, First of all, we have no clue what the units in the picture from Rignot are (cm/day, m/year?) we should compare your results to - if you used the attached SIF your Elmer/Ice velocities are m/year. Looking at your SIF you have a no-slip condition at the bedrock, which kind of contradicts...

Re: some units problems when I join the sliding section

Hello, the units (and hence the value) of the coefficient for the sliding law depends on the rest of you units. Elmer doesn't restrict you on that. If you use SI units (m-kg-seconds) then the unit for the friction coefficient (the beta^2 as decribed for instance in ISMIP-HOM experiments for linear s...

Re: ctest failed due to segmentation fault errors

One more hint I got yesterday from a colleague for OSX: one frequent cause of troubles could be the Blas library provided by Apple. If I understood correctly, there might be a way to replace it by one from homebrew. Dunno if this helps

Re: ctest failed due to segmentation fault errors

Hi Michelle, we are working on a documented plan how to install on OSX. For your CentOS installation: you definitely want to have MUMPS and easily can forget about Hypre if you are doing glaciological problems. On RHEL I found a RPM package for MUMPS in the EPEL repository and this looks very promis...
