KVK,

we are looking into your case files.

For the above error, please check your RASProperties files in constant folder.

Hi Rahul Joshi ;
I have checked RAS properties in Constant folder and made necessary corrections. When i am trying to run the simulation i am getting the error as follows

Hi Rahul Joshi;
I have solved the problem with RAS properties in constant folder . But when i am running the simulation i am getting an error as follows

Please help me how to solve it.

This error usually comes when fvOption is missing in system directory.

Try running this case by putting your case directory inside the interFoam solver.


01-04-16, 8:13 a.m. rahuljoshi
can you please tell me step by step procedure about how to put my case directory inside Inter foam solver ?

There is a tutorial folder inside your OpenFOAM directory.
Inside which there is a folder named multiphase , in which you have interFoam solver ( directory ).
Put your case inside that directory. 
01-04-16, 8:30 a.m. rahuljoshi
I have done what you have said but i am getting the same error

Can you post your velocity and pressure files here. The error points out that there might be some issue with the boundary conditions that you have set,  which is not satisfying the continuity equation.

Did you check the boundary conditions. ?
04-04-16, 4:03 p.m. rahuljoshi
Yes, I did


06-04-16, 9:07 p.m. KVK
You have posted the p_rgh file which is the dynamic pressure.The type of boundary condition used here is  fixedFluxPressure, but you have not specified the value for for this flux pressure .

/*********************************

type            fixedFluxPressure;
value           uniform 0;

/*********************************

 Also why are you using two different versions of OpenFOAM. In the header it shows 3.0.1 for the U file and 2.3.1 for p_rgh file.
