Re: Elmer-8.3 -- Maximum Output Level 40 gives huge output
Hi Peter, Thanks for your reply! I thought that the Max output level is 42. Anyway in my Elmer version, this happens from Max Output Level 22 onward. As far as I can see, this happens between the two function calls: CALL StartAdvanceOutput('....Solver','Assembly' ) and CALL Info( '....Solver', 'Asse...

Re: Navier-Stokes in a volume
Hello, Looking at your sif - a few comments. Air Flow inlet velocity is 10 m/s, so the flow could be turbulent: use a turbulence model, for eg. kepsilon. Also remove NS Convect = False from Equation 1 - you need convection. Didn't quite understand why you used two materials - air and ideal gas. If t...

Elmer-8.3 -- Maximum Output Level 40 gives huge output
Hello, I used a newly compiled version of Elmer-8.3 (compiled on ubuntu 14.04 using CMake as instructed here: http://www.elmerfem.org/forum/viewtopic.php?f=2&t=3742) and found that declaring "Maximum Output Level = 40" results in very large output files. In the new version, right after...

Re: Restart file (i.e. Output File) pruning?
Hello,
Have you found a solution to this issue? Is it possible to save restart files less frequently than what is controlled by the keyword "Output Intervals = .." in the Simulation section?
Thanks/Regards
Kumar

Re: Failed convergence tolerances
Also, the Noslip Wall BC = True might result in problems with the k-epsilon model if the boundary layer is not fine enough. Please remove this and change all the walls to something like:
Wall Law = True
Normal-Tangential Velocity = True
Velocity 1 = 0
Boundary Layer Thickness = 0.01

Wall Law = True
Normal-Tangential Velocity = True
Velocity 1 = 0
Boundary Layer Thickness = 0.01

Re: Failed convergence tolerances
Hi, Reynolds no. is perhaps not an issue if the case is 2D. Please turn in a turbulence model (k-epsilon) and run the case with the following settings: Solver 1 Equation = Navier-Stokes Variable = Flow Solution[Velocity:2 Pressure:1] Procedure = "FlowSolve" "FlowSolver" Stabilize...

Installing Hypre after Installing Elmer
Sometime back I installed Elmer binaries on Ubuntu 14.04 from the Launchpad by the sudo apt-get method. It is working perfectly and I would now like to install Hypre and link with the Elmer executables already installed. Is this possible without uninstalling Elmer and recompiling Elmer and Hypre tog...

Turbulent Flow with Heat Transfer
Dear Elmer Users, I need to estimate the heat transfer into an immersed solid body from a reasonably turbulent stream flowing past. Standard k-epsilon model will be sufficient to model the turbulence. It is my understanding that thermal functions are not implemented in the Reichardt's wall law for t...
