Hi! I'm trying to achieve convergence in my kwSST simulation and one of the parameters that I want to change is the div(phi,U). I have checked on Openfoam's website and apparently the only thing that has to be added on fvSchemes is:

Code:
divSchemes 
{ 
    div(phi,U)          Gauss DEShybrid 
    linear                        // scheme 1 
    linearUpwind grad(U)          // scheme 2 
    0.65                          // DES coefficient, typically = 0.65 
    30                            // Reference velocity scale 
    2                             // Reference length scale 
    0                             // Minimum sigma limit (0-1) 
    1;                            // Maximum sigma limit (0-1) 
}
But when I add this (I'm using 3.0+, of course), the error output is:

Code:
--> FOAM FATAL IO ERROR:
Unknown discretisation scheme DEShybrid
Valid schemes are:
...
Does anybody know where the problem could be? Both DEShybrid.C and DEShybrid.H are on the src folder...

Thanks in advance!

Hi,

you have to include the library (where the Scheme is located in) in your controlDict.

Best regards,
Jan

Include this library at the start of your controlDict, it should work then



libs (turbulenceModelSchemes);

application pimpleFoam;

startFrom startTime;

startTime 0.;

stopAt endTime;

endTime 0.005;

deltaT 0.0001;

writeControl adjustableRunTime;
saeed jamshidi, Gang Wang and xCFD like this.
