Hi!
I guess, in order to help you, we need the SIF file and the mesh, you used.

Re: 3-Dimensional Natural Convection
Hi!
I just have look at SIF. I don't try to run the case.
One thing, I've spotted is:
In 3D case it should be
in order to initialize three components of Velocity vector.
Good luck!

Code: Select all
Variable = Flow Solution[Velocity:2 Pressure:1]
Code: Select all
Variable = Flow Solution[Velocity:3 Pressure:1]
Good luck!

Re: Failed convergence tolerances
Yor're welcome Anil ;) In addition to previous post I'd like to share transient version of sif. Quite funny results obtained. First the flow moves forward and symmetrically. I thought previous steady simulation is wrong... But after thinking some time the flow decides where to go. With different set...

Re: Failed convergence tolerances
Hi, dear Cristobal! In incompressible flow inlet and outlet velocities have to be equal. That is not observed on specified picture. So, we have to do something. I played around with Cristobal's reactor and I want to share the results. I have prepared a non-GUI case and obtained the results. First of...

Re: k-epsilon model for turbulence
Hmm...
It is strange. I just have downloaded your project, load it to ElmerGUI and press "Start". Convergence was reached after 46 iterations.

Re: material for thermal/heat simulation
Hi!
Heat eqn. besides heat conductivity includes heat capacity and density. So, if you do not specify these parameters, you will not be able to solve Heat eqn. correctly
Regards, Dmitry!

Re: k-epsilon model for turbulence
Hi, Saaddin! You missed one important thing. Amount of Nonlinear iterations of both solvers have to be equals one, as mentioned in tutorial. Nonlinear System Max Iterations = 1 Oterwise Elmer try to solve only NavierStokes eqn. first and it do not calculate k and e after NavierStokes iteration. The ...

Re: k-epsilon model for turbulence
I guess, you should provide your last try (sif file), then we can understand, what to do.

Re: Multi-phase flow simulation 2D - Level Set Method
Hi, Peter! Thank you for your detailed comments!
Elmer cover some fields of my interests, but, I guess, it's inevitable to start learn OpenFOAM, if I want to deal with free surfaces effectively.

Multi-phase flow simulation 2D - Level Set Method
Hi dear Elmer users! I want to share a non-GUI case of 2D multi-phase flow simulation by the means of Level Set Method. Falling water column simulated here. Case is based on "levelset3" test. Also present post touch on a matter of following topic (Density ratio of phases 1/1000): http://ww...
