Re: MPI problem

Hi,
could you perhaps check in Synaptic, whether you accidentally have hypre installed and hence the library within your paths? The config.log from the fem-directory would help to inquire that.

Regards,

Thomas

Re: Zeta potential not working?

Dear Sebastian, on a first look I had I think there's something not OK with your mesh or I have issues in understanding what you are after. Three issues I found: 1) the left side boundary for me appears not to be defined all over the height (just load the mesh into ElmerPost and display all lines an...

Summer Trainee Elmer

CSC is looking for a summer trainee to help implementing and develop Elmer modules for effective data I/O in parallel environments, in particular for climate related data stored in the NetCDF format. This includes automated interpolation data and coordinate transformation of coordinates. Time permit...

Hello,
this is just a guess, but you might be in need of either setting the libraries in LD_LIBRARY_PATH or the LDFLAGS ...

Re: Axisymmetric to 3D view

Hello,
to my information it is not possible to revolve axi-symmetric results inside ElmerPost. That would demand major modifications of the *.ep result file.

All the best,

Re: Application fields of Elmer

There are about 10 - 20 users (with a core of about 5 high level users) in Earth Sciences, mainly in Geophysical Fluid Mechanics in Glaciology, spread over the globe that I think should be presented in this statistics.

Re: How to display an additional field variable?

Dear Peter, Apparently things go wrong if a variable with the name Density is added by SaveMaterials. I have the suspicion that this is connected to the fact that Density is in the Elmer keyword database (hence a reserved name). If you give it another name, like for instance Dichte , and simply assi...

Re: How to display an additional field variable?

Dear Peter, I could reply your error with a different, but similar case. When I drop the SaveMaterials (Exec Solver = Never), the run survives. Can you confirm that this is also the case for you? I checked with a debugger, but actually did not find an issue directly in SaveMaterials. Will try to hav...

Re: communication between partitions in parallel

Hi Lionel, in parallel computing communication (i.e., utilizing the MPI calls) is the main cause of performance limits. The less your parallel tasks have to talk to each other, the more they can spend on doing the number-crunching. Especially if you use blocking communication (when often CPU's are i...
