Pulverized coal and slagging TUTORIAL

Hello everyone: I have been trying to replicate the CS 3.2 tutorial "Simulating pulverized coal combustion, coal/biomass co-combustion and slagging in a furnace using the Lagrangian approach in Code_Saturrne" and I have found several troubles I would like to be helped with. - The first par...

Meshing programs

I have read several topics concerning the meshes quality-dependency of the simulation results (or worse, simulation failures), and I would like to inquire to the community what meshing program are most adequate for complex geometries. In my case, probably because I began the Code_saturne usage in CA...

About the "floating point exception" error

Hello everybody: This is not an original thread as there are many people posting the same error as it seems to be a error related with several sources which may lead to a common end: a division by zero, and this result may be because of a property calculation, a boundary condition mismatch etc. Am I...

Re: Lagrangian simulations - Additional variables

Hello Yvan: Thanks to the use of the CS_LAGR_USER attribute, now it works so that the personal lagrangian property is being calculated and post-processed. I have used CS_LAGR_USER+0 as a pointer for the first property extraction, I will test several properties calculation simultaneously to check if ...

Re: Lagrangian simulations - Additional variables

Hello Yvan: Thanks to your suggestion now the simulation is able to store and represent the values of a different result differente than the typical ivisv1, ivisv2, ivisdm,... etc., but to be honest, I think I am lost with what is being represented or why are the values so different to what it was e...

Re: Lagrangian simulations - Additional variables

Hello Yvan: Regarding your questions, I answer: The tests has been perfomed on the velocity values of each particle, in two different ways: - First: Read the value of "y" direction velocity for each particle, store in an auxiliary variable and show it in the "calculation screen" ...

Re: Lagrangian simulations - Additional variables

Hello Yvan: I have installed the Code_Saturne 3.3 from scratch in an Ubuntu 14.04, and I am not able to find the cs_post_default.c file, so I can't find where should I write the extra lines in order to be able to compile it and so, test it. May the function cs_post_write_particle_values function pla...

Re: Lagrangian simulations - Additional variables

Hello Yvan: First of all, thanks you for the quick answer to this doubt. I guess from your answer that the proposed solution (the one which implies the addition of several group of lines to the cs_post_default.c file and its copy to the simulation SRC directory) could only work in Saturne 3.3 , whic...

Lagrangian simulations - Additional variables

Hello everybody: This is my first post both in this board and in Code_Saturne community so, first of all I think a brief introduction should be mandatory: My name is Pablo and I am performing my PhD with Code_Saturne since a (relatively) recent time. Because of my academic/professional past I have s...
