Summary | 0001324: non-zero velocity can not be set to blockage wall of cyclicACMI | ||||
Description | I am trying to do tutorial of cyclicACMI with OF2.3.x oscillatingInletACMI2D. I can not set non-zero velocity on ACMI2_blockage. fixedValue (0 0 0) is default setting. I want to set fixedValue (10 0 0) on the ACMI2_blockage of U. But it didn't work well. it became fixedValue (0 0 0) as time progresses. | ||||
Steps To Reproduce | Set the following on ACMI2_blockage of U file ACMI2_blockage { type fixedValue; //value uniform (0 0 0); value uniform (10 0 0); } | ||||

I'm having the exact same problem in a custom interDyMFoam run. The alpha.water BC on the blockage patches resets to ACMI2_blockage { type fixedValue; value uniform 0; } even though I'm specifying ACMI2_blockage { type fixedValue; value uniform 1; } I think this issue: http://www.openfoam.org/mantisbt/view.php?id=1335 is also related, as I also get incorrect low values of alpha.water next to the blockage patch when using zeroGradient as BC. That's the reason why I tried using fixedValue as BC on the first place. |

Hi I found the other way to set non-zero velocity on blockage wall of cyclicACMI. timeVaryingUniformFixedValue has to be used instead of fixedValue. Actually,timeVaryingUniformFixedValue seemed to become obsolete in OF2.3.x. But you can use it of OF1.7.1. I attached "oscillatingInletACMI2D" being set timeVaryingUniformFixedValue on ACMI2_blockage of U. I am very happy if this could help someone. Plese don't forget wmake libso timeVaryingUniformFixedValue before running. Regards, kkk |

timeVaryingUniformFixedValue has been superceded by the more general uniformFixedValue BC which support various ways to evaluate the "value" including various functions of time. This functionality has been further enhanced in OpenFOAM-dev. |
