Hi to everyone,
i'm having a problem with OF especially with the combustion case with the tool reactingFoam. i'm trying to do this tutorials (https://develop.openfoam.com/Develop.../RAS/DLR_A_LTS) but OF gives me an error:

does anyone know why?

thnks to all that will answer me

Hi ade10, I think that the problem is due to how you write the entries in thermophysical properties since you are using V9 and the tutorial is from V2112. I suggest to check in V9 tutorial folder for the same case and seeing how they write down the entries. Let me know.

Hi ade10,



Did you solve this problem? I am stuck on it too.



The tutorials I am using have outdated mixture commands, but updating to multiComponentMixture was straightforward.



The "keyword specie is undefined in dictionary...." error persists.



For what it's worth, I am using the tutorials that came with my installation.



Thank you,

Erik

Hi Erik, can you show as the thermo physical properties files and tell also which tutorial and version are you using?

Hi Erik,
yes i've solved the problem.... I was using of.org and it wants some things written differently from of.com

you can try this:

Hi Alessio,



Thank you for the response!



I am trying the tutorial counterFlowFlame2DLTS.



I think I may be confused about which version I am using. When I run blockMesh, it says version 9 :


/*---------------------------------------------------------------------------*\

\\ / O peration | Website: https://openfoam.org
\\ / A nd | Version: 9
\\/ M anipulation |
\*---------------------------------------------------------------------------*/



.
.
.


But my tutorials are for v2106. Below is the thermoPhysicalProperties file.



Based on ade10's reply, I learned that there are two different "flavors" of openfoam. Are there compelling reasons to use one over the other?
