Re: Convergence troubles with large domains

Hello all: According to Yvan's suggestions, I have extruded the outlet boundary faces as it can be seen in the following image: http://s27.postimg.org/6tx4qrjgz/EXTR_OUTLET.png ...which only represents a small variation on the element number. I have re-run the simulation with the new mesh but the va...

Re: Troubles with Pulverized coal and slagging TUTORIAL

Ok, so, my next doubts are: -|Doubt no.1 |-------------------------------------------------------------------------------------------------------------------------------------------- According to what you said, the src/lagr/lagsta.f90, I guess, copied in the DATA folder of a certain simulation would...

Re: Convergence troubles with large domains

Hello Bryan: Where do you see those cells in the check_mesh.log? As far as I can read, the quality criterions shows: Criterion 1: Orthogonality: Number of bad cells detected: 0 --> 0 % Criterion 2: Offset: Number of bad cells detected: 0 --> 0 % Criterion 3: Least-Squares Gradient Quality: Number of...

Re: Troubles with Pulverized coal and slagging TUTORIAL

Those options only allows to defined whether to select them or not, but I still can find where those laws are defined.

May be within the pre-defined uslag/uslag2 files for the slagging simulation?, where are them in the simulation?

Kind regards

Re: Convergence troubles with large domains

I attach details of part of the geometry domain (the whole flow domain has been divided so that a step-by-step simulation can be performed): http://s9.postimg.org/9muklvnxb/Screenshot_11272014_01_35_55_PM.png ...and details of the mesh: http://s7.postimg.org/nql40agsr/Screenshot_11272014_01_41_20_PM...

Re: Troubles with Pulverized coal and slagging TUTORIAL

Regarding this tutorial, and analyzing its behaviour, the post-processor shows certain variables such as: "Part_statis_weight" "Part_bndy_mass_flux" "Part_fouled_Xck" "Part_fouled_diam" ... ...which are not defined (or I am not able to locate them at least :oo...

Re: Troubles with Pulverized coal and slagging TUTORIAL

Hello Yvan: I have achieved to complete the deposition model, although, to be honest, I stil does not know which was the simulation failure. I have "debugged" the XML file comparing the two-fueled simulation against the simplified-one-fuel simulation so that I could find the differences su...

Re: Troubles with Pulverized coal and slagging TUTORIAL

Hello Yvan: The Code_Saturne version I am performing these simulations is 3.3 I have performed two different cases: - CASE tutorial , according to the exact steps shown in the 3.2 tutorial. - CASE simplified , using just one of the components (coal) of the tutorial. I have been working on this CASE ...

Re: Troubles with Pulverized coal and slagging TUTORIAL

Although this is a self-reply, and maybe it is not the most adequate way to organize the forums, I think it could be better for an easier comprehension of the problem as well as the evolution. -----------------------------------------------------------------------------------------------------------...
