Time Dependency/ Scale Mesh/ Wall Definition
Hello,
I am fairly new to OpenFoam and thus with that come many questions. In any cases with OpenFoam its dependent on the Courant Number. If I enter the controlDict you can define deltaT. Now my question is in regards to steady state cases. Is deltaT time dependent or time iteration dependent? If time dependent why? Next question: How do you scale the mesh? I have a .msh file created in Gambit (completed the fluentMeshToFoam) simple 2D case (channel flow, d=1m) I would like to scale my geometry but only in the x direction ie, change the diameter to 1 cm instead of 1 m. Is this possible in OpenFoam or does the geometry need to be changed in the originial Gambit file? Final Question: In the boundary field how do I know which wall is which? ie in the icoFoam/elbow case there is 2 walls defined (wall-8, wall-4). |

Hi Robyn,
this might solve your scaling problem: fluentMeshToFoam -case <case> -scaling '(<xFactor> <yFactor> <zFactor>)' just scale x-Direction: '(0.01 1 1)' |
Thanks for the response! I'll test it out.

hi friend
the correct form of scaling command is like below , if u have any hint which help me to have various scaling in different direction it can be helpful fluentMeshToFoam balbla.msh -scale 0.1 or fluentMeshToFoam balbla.msh -scale '0.1' |

foamToVTK and then start paraFoam and then open "File/Open" the "VTK"-folder that has been created with foamToVTK. there you can open the main body and the patches, so you can see what is what, by clicking on the "eye" next to the patch name or main body. regards |
