Elmer Discussion Forum

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...

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...

Noticed that the log file is not uploaded. Here it is.

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...

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

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

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...

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...

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...

I tried to install Elmer using the Launchpad option by adding the repository and using apt-get install as described here: https://www.csc.fi/web/elmer/binaries The installation does not proceed and gives me the error message: Reading package lists...
