Hello!
I am a new user of Ope
Hello!
I am a new user of OpenFoam. I was looking at the damBreak case and nozzleFlow2D case. Both the cases require setting a non uniform gamma field. However, the damBreak case uses setFields utility to do this while nozzleFlow2D uses cellSet utility. Is there a particular reason why this is done? When I looked at the user manual, I saw that both these utilities are for selecting a cell set through a dictionary- one does it in preprocessing while the other does it in mesh manipulation. Can somebody please help me know why two different dictionaries are used here? Thanks, Suraj |
Velocity Boundary condition on Imported 3D Mesh
Hi,
I wanted to specify the given Velocity Boundary Condition varying with distance from Base of Fluid Domain).For this I have created a Body and have done meshing on it,then imported in openFoam.I have tried using inlet { type fixedValue; value nonuniform List<vector> 45 ( (0 0 6.7) (0 0 6.8) (0 0 6.90)... There was a option for specifying velocity vectors at the specific patches(given above), but I am not able to understand how to specify faces for each velocity vector in the Inlet patch of the imported Mesh. Alternatively, Is there is any option to specify the Height of the vectors they are acting at?? Abhishek |

Imported Mesh
Thanks for the reply
But I have a doubt does it work for IMPORTED Mesh as well, if so then how do we apply setField there. Abhishek |

Have you managed to import the mesh into the OpenFOAM case? Can you share the case? Or at least provide a simple test case so that it's easier to show you how to use setFields. More details available here: http://www.cfd-online.com/Forums/ope...-get-help.html |
non-uniform velocity profile
hello everyone
I'm using OpenFoam for my study and I would like to specify non uniform initial conditions for my case (velocity). Can someone tell me more about that. I'm a begenner and I have no idea how to do it thank you |
