Re: Can I solve this with Elmer
Hi, Unfortunately not. The little work on contact models has been experimental and limited in functionality. -Peter

Re: Helmholtz solver excitation at selected node
Hi Create a new BC section and instead of refering to "Target Boundaries" give "Target Coordinates". The closest node to the coordinate value will be chosen, for example Boundary Condition 7 Name = "FixedNode" Target Coordinates(1,3) = 1.2 2.3 0.0 Pressure 1 = Real 0.0 ...

Re: Combination of .vtu results
Hi
This should not be needed since many programs, such as Paraview and ViSit, can read the partitioned data. Just open the .pvtu file therein.

Re: Adaptive Timestepping
Hi I would never have found out by myself what you have suggested (timestepping method = explicit Euler - what is that, and why is it better here? etc. etc.). Time integration methods such as the explicit Euler are not limited to just to FEM. In fact in FEM the time discretization is the only one th...

Elmer channel on Youtube
Hi All, Just for the fun of it, there is now a youtube channel for Elmer movies. See http://www.youtube.com/user/elmerfem It's biassed towards some fresh developments on particle trackers but hopefully with time it will more representative to all the features of Elmer. If you have, or intend to put,...

Re: Divergence (with NaN steps) for Navier-Stokes equation
Hi About ElmerGrid and gmsh: If you do not use physical entities then by default the mesh is cleaned and renumbered. This means that the '-autoclean' flag is enforced. This is because the default numbering of geometric entities is not ideal for Elmer. Also gmsh does not seem to be consistant with th...

Re: freesurfacesolver for droplet motion?!
Hi I think that your approach might be almost feasible. The thing that worries me little bit is the triple point where the plane, air and drop meet. If you use no-slip conditions for the velocity it will also fix the triple point (or line in 3d). Having a suitable slip coefficient might result to be...

Re: Divergence (with NaN steps) for Navier-Stokes equation
Hi, You should apply the "exec solver = never" to the k-epsilon solver, not to the flow solver. -Peter

Re: Few question about convergence and preconditionals (ILU)
Hi Althenor 1) I created yesterday a subforum in which people can submit their cases of moderate size. One could place to look is the "tests" directory in your Elmer installation which includes around 140 minimalistic Elmer cases. 2) If you do *exactly* as in the tutorial there should not ...

Re: Divergence (with NaN steps) for Navier-Stokes equation
Hi
To remove the turbulence model say for the turbulence solver
Comment out the "Heat Condutivity Model" and "Viscosity Model", and set the tangential velocity components to zero.

Code: Select all
