Hi everyone, I have workin
 
Hi everyone,

I have working with a simpleFoam case to see the flow of air from a inlet to outlet on a specified path.

The mesh has readed from a third party client and boundary patches are set in constant/polymesh.
The control dictionary were set to read for 300 as end time with a write interval of 100.

The fvsolution &t the intial boundary conditions
are feeded.

When I running the '0' time folder for simpleFoam

I got the following error
Application started with pid 22270

Kindly advice me where i did wrong

Thank you,

Hi,

I am also working on a problem and encountering the same error. Did you find a solution for this error?

Hi Mayank,


Welcome to the forum. Since the first post dates from 2008, I doubt Hariya03 will reply ;-).

For which field do you get this error? Can you post your boundary conditions file of this field (the file in the 0-folder)?

Cheers,

L

Hi Lieven,

Thanks for your reply.
The problem is solved.

I am very new to OpenFOAM. As a part of my thesis, I have to run simulations on OpenFOAM involving fluid particle dynamics.I am trying to set up a 'one way coupled' case for running application 'icoUncoupledKinematicParcelFoam' on a standard driven cavity as a test case. Below is my approach:

1.) I ran 'icoFoam' driven cavity tutorial and picked up the velocity field(U) from the directory created at last time step i.e 0.5.

2.) I used this velocity field as a pre-defined velocity field for running 'icoUncoupleKinematicParcelFoam' by putting in this velocity field inside '0' directory of a new case set up using the same driven cavity mesh. This time I included all the necessary files required like 'KinematicCloudProperties', 'KinematicCloudPosition', 'turbulence properties' etc.

3) The case ran fine without errors.

Is my approach for setting up one-way coupled cases using a pre-defined steady velocity field ok or is there a better way for performing one way coupling? Also, I am new to this forum please guide me if I am asking this question at a wrong place.

Regards,
Mayank
