Hello Jundi He, Please check the value of the head loss (K) in the "Free inlet/Oulet" boundary condition. By default (in my cases) this value is not setted and give me a similar error. But if you say that the error appears only when you activate the radiation module I do not think this is ...

Hello kathi, The tool to convert a mesh created in salome (* .med) to a mesh to be used in Syrthes is "convert2syrthes4", and it is provided as a Syrthes tool. For the results file, inside of syrthes you have to go to "Running options" , "Advanced Options" , "Conve...

Hello, Yes, using Salome you can export a mesh surface as a *.DAT file, in the first line you get the number of nodes and the number of element, then the list of nodes (global node ID , coordinates) and then the list of elements (global element ID, conectivities). Also, you can do it using Paravis a...

Hello, In the section "Running options" of Syrthes you have the "Advanced Options" and you can choose "Convert results for software" Ensight/Paraview. This will convert the *.res to *ensight.case. Then you can open in Paravis and apply the filter ExtractSurface and then...

Hello, The numbering of nodes and connectivity elements are given by the mesh generator (netgen, gmesh, etc.), but a format conversion (med-> syr) is needed, changing the way in which the information it is stored and organized and be able to be readed by syrthes. In don't understantd very well your ...

Hello Jundi He, Syrthes (conduction problem) is based on Finite Elements Method (FEM), while code saturne uses finite volumes (FVM). In FEM the unknow (temperature) are in the nodes, not in the cell center like in FVM. The global numeration of nodes goes from 1 to the total number of nodes and it is...

Hello Kenneth, In the listing file the output is setted at the end of the calculation and I can find where it is defined the saving frequency that you mention. Screenshot_20170131-222649.jpg Also in the Result.case the time value it is 122.44, which correspond to your last time step. In the case of ...

Hello Jundi He,

Did you solve the problem? If not check the stderr.txt file for more information. Also, you can check the in the user_fct.c file (void user_cfluvs_fct() ) if the data that you input throught the GUI were setted.

Regards,

Luciano

Hello BruceS, Code Saturne by default sets 4 restarts checkpoints during your simulation, you can change this frequency in "Advanced options" in the "Start/Restart" tab. If your simulation does not reach almost the first checkpoint (1/4 of the whole simulation) the directory &quo...

Hello Kenneth, Going to your first post, you have mention that you can not visualise the temperature contours in every second in ParaView. Checking the listing file and the xml you have set the postprocessing output "at the end of calculation", wherewith you will have only one output....at...
