Hi
Ive read the chapter but i couldn't find the specific keywords needed to set this particular boundary condition. Maybe there's something im missing, but any hints would be most appreciated
Thanks

Velocity Flux across boundary
Hi
I'm running a N-S solver, and im trying to impose a constant normal velocity flux boundary condition, but i can't seem to find the right keywords to do so. How would one go about doing this?
Thanks

Re: Multiple body STEP meshing with Salome
Hi I managed to create multiple bodies using this method. However, when i reopen the mesh in salome, and look at the individual meshes for each body, it is no longer the shape of the geometry group. Instead, there are elements missing within the mesh and extra elements floating around it. I was wond...

Navier Stokes Convergence Issue
Hi I am having convergence issues with a coupled thermal and flow simulator. The mesh is of a metal geometry with a block of air above it. At first the simulation converged for the first 40 time steps, but then i realized i had set the initial and boundary pressures to 0 instead of 1e5 (100 kPa). Bu...

Dynamic Relaxation Factor
Is it possible to set a dynamic relaxation factor, as in a relaxation factor that depends on the change in the norm?
Additionally, how would one call the value of a variable from a previous time?
Thanks

Re: Solver to pause elmer until a change is made
Hi
Thank you for your response. Where could i find the documentation for SystemCommand()?

Solver to pause elmer until a change is made
Is it possible to write a solver that pauses a transient simulation at a certain time until a text document (or other external file) has been updated?
