Re: Save Data and boundaries and partitions

Hi, if I might add one comment to the presented solution. The DummySolver was just run on the body for which you want to have the volume computed in order to create a variable (DummyVar) that has the needed permutations (only existing on that very body). If you have such a variable already at hand, ...

Re: infinite MeshVelocities

I think, by keeping the geometry constant in c), you also should omit any ALE related corrections, i.e., keep Mesh Velocity at zero.

Re: infinite MeshVelocities

Martina, if you anyhow do not need the Mesh Velocity, why don't you set: Compute Mesh Velocity = Logical False ? Why does it produce non-sense?: In the code it reads as follows: MeshVelocity = ( MeshUpdate - Solver % Variable % PrevValues(:,1) ) / dt My suspicion is, that you have dt=0 in case of st...

Re: Basal Friction cooling

Hi Denis, with the help of Joe we found a bug in USF_GetFrictionHeat.f90 that might explain your problems. We have a new version and we are testing it at the moment. I will send a message to the list once things are completely fixed and a test-case has been set up. Sorry for the inconvenience, Thomas

Re: Problems with GridDataReader

Hi, I know, that comes ridiculously delayed, but we have had fixed that for Jaime already during the Elmer/Ice advanced workshop. Nevertheless, for the records (should someone else be interrupted by a similar issue): That error is likely to occur when forgetting to link the correct libraries and/or ...

Re: Outflow natural boundary when v.n is outward

Denis, it is odd that you do not get any error message. What I could think of is, that you perhaps dash into an issue if you evaluate this condition before the variables you need (Velocity and Normal Vector) have been assigned with a value, hence leaving the Temp Cond with Zero. A Initialize Dirichl...

Re: Nanoparticles in a plasma

Laura,
you might consider to have a look at the ElmerModelsManual and check out the ParticleDynamics Solver - it has drag, particle-particle collisions and certain type of damping included.

Regards,

Re: Small basal velocity value patch from Adjoin inverse method

Hi, I am not that sure if there's something wrong. As we discussed today and from your latest picture you can deduce that you are comparing the measured velocities at the surface with the computed at the bedrock. The match at the surface (not shown here) was visually quite OK and also your L-curve w...

Re: Restarting Advection Reaction Solver for Age Equation

Dear Reinhard, there seems to be an issue with rereading a DG solution into a parallel setup - I presume your wiggles of the reread age profile coincide with domain boundaries, right? - but the DG stuff anyhow comes with a big warning attached to it. As I understand it, your idea of using Olivier's ...
