HI, Martin, how to realize that the transport properties like nu and DT is a function of temperature in the OpenFOAM? Best regards. Can you help to send a revised solver and simple case as you revised in this topic?

I am using OpenFoam 2.2.0.

I downloaded the case and solver of Martin ( post 31) but i could not run the case.

Output:
Code:
abm5kor@BMH301562:~/Downloads/case_of2$ mySimpleFoam
mySimpleFoam: command not found
any idea ?

You should first compile it.
enter in the mySimpleFoam directory and run wmake.

Best

As you could not the case, i copied the the simpleFoam-solver in my Home (i followed the tutorial How to add temperature to icoFoam ) and i copied the data content of mySimpleFoam.C in my my_simpleFoam.C.

The case is now working but i got same this warning for every timestep :

Code:
Time = 0.03

how can fix the warning?


Thx

Thx for your answer

i cannot compil it :

Code:
abm5kor@BMH301562:~/OpenFOAM/abm5kor-2.2.0/applications/solvers/my_SimpleFoam$ wmake
make: *** No rule to make target `my_SimpleFoam.dep', needed by `Make/linux64GccDPOpt/dependencies'.  Stop.

I guess you should update the fvSchemes and fvSolutions files to the latest version you are using.
You can find these files into one of the tutorial case in your openfoam installation.

Do you think, that i could not compile the new solver, because i did not used the latest version of fvSchemes and fvSolutions?

i understood , what i mean Andrea
i need the latest version of fvSchemes and fvSolutions, only for running the case

hi every one
i have a problem with solution "damBreak" tutorial in OpenFoam with rasInterFoam solver.when i type " rasInterFoam " in terminal , it seid " rasInterFoam: command not found " !! do every one how can i solve my problem ?
version of my OpenFoam is 2.2.1 ; it hasn't rasInterFoam but in folder of interFoam ( or many of other solvers) it has "ras" and "les" folder . and my damBreak folder has " RASProperties " .

Hey jvd.mechanic,

there is no rasInterFoam in 2.2.1. Just use interFoam as it is supports generic turbulence modeling like RAS, LES or laminar. Just set the constant/transportProperties and RAS/LESProperties according to the model you want to use.
See here:
$FOAM_SOLVERS/multiphase/interFoam line 34:
Quote:
Turbulence modelling is generic, i.e. laminar, RAS or LES may be selected.

yash.aesi is on a distinguished road
Greeting Martin and all ,
i am using OF-2.2 and i need to find scaler dissipation rate (chi) of the cold flow for that i have to add mixture fraction variance (Zvar) equation into the existing solver, as
chi= Cx * epsilon/k * Zvar
so now i had made separate my_simpleFoam solver but not getting idea how to proceed further. so can somebody guide me through this problem

Thank You,
Regards,
Sonu

flowAlways is on a distinguished road
Hello,
Can someone please explain me.
What does adding temperature to simpleFoam solver essentially means?

Does it mean

1. That we want to obtain both the flow field and the temperature(not coupled) distribution
and if so why not use scalarTransportFoam after obtaining the flow field using simpleFoam ?

or

2. If we want to consider a strong coupling of the flow field with the temperature distribution(which effects the density and viscosity) why not use rhoSimpleFoam ?

or.

3. we consider small variations in temperature and thus density in which case we can use buoyantBoussinesqSimpleFoam.

Please if someone could illustrate. I am confused.
I want to model a burner with turbulent reacting flows and I started with laminar flow, isothermal turbulent flow and next I want to learn non-isothermal turbulent flow. But I dont understand which model will be the best suited for the last case?
