Hello,
Has anyone tried to use multiple lua files with modules and use these files in an elmer sif file?
I am having difficulties accessing constants defined in a lua module inside the sif file. Any help appreciated.
Thanks
Denis

Re: Periodic BC Rotate
Hi Peter, Thanks for the tip. It now works. However, in this 3d problem, there are issues at the edges of the different boundaries. The velocity is not enforced properly (see attachment with views of velocity vectors). This gives some not very physical values of velocities at edges and corners. How ...

Periodic BC Rotate
Hi, I have this geometry (see image) and need to enforce a periodic boundary (between inlet and outlet). There is a 30 degrees rotation along the z axis (vertical, out of image) to bring the inlet back onto the outlet. The problem is 3d. How do I enforce this poeriodic bc in my sif files? what I tri...

Re: Periodic BCs in parallel
Hi Peter, Reopening this post. I also have periodic bc in parallel. Tried the -periodic but that crashed: $ ElmerGrid 2 2 mesh3d_fit -metis 4 4 -periodic 0 1 0 Starting program Elmergrid Elmergrid reading in-line arguments The mesh will be partitioned with Metis to 4 partitions. Output will be saved...

Thanks Peter,
The transformation is working beautifully.

Re: Converting Gmsh file to Cylindrical Coordinates
Hello,
Related topic, I would also like to know if inside ElmerSolver there is a way to convert a 3D r/theta/z (cylindrical) mesh to a 3D x/y/z mesh.
I assume that the Navier Stokes solver and all it's functionality (e.g., periodic bc) does not work in r/theta/z coordinate system.
Thank you
Denis

Basal Friction cooling
Hello, I am getting strange results when I turn on basal friction. My bed is cooler (lower temperature) than if I don't have basal friction. I suspected the other way around. I've been following the instructions on the wiki to set it up. Has anyone noticed such behavior? Is there a sign problem? Tha...

Hi Thomas,
Thanks for the info. It's running now. Will check results.

Outflow natural boundary when v.n is outward
Hello, I don't want to impose a Dirichlet Temp BC when the surface velocity is out of the free surface (v.n >0) so I have this in my top surface BC: Temp = Variable Coordinate 3 Real MATC "min(273.15 273.15-5.3-0.006*tx)" Temp Condition = Variable Velocity 1 , Velocity 2 , Velocity 3, Norm...
