Summary | 0002836: compressibleInterDyMFoam, Mesh Morphing issues | ||||
Description | Related to the previous case https://bugs.openfoam.org/view.php?id=2824, which has been solved, I see still some wrong behavior using the mesh morpher in compressibleInterDyMFoam (dev-version 20180205). First of all, thanks Henry for taking time and looking at it. Really apreciate that. Using the mesh morpher with this settings in dynamicMeshDict: velocityComponentLaplacianCoeffs { component x; diffusivity inverseDistance (fixedArc); } produces an unphysical density/temperature-distribution along x-axis(see attachement: compressibleInterDyMFoamMeshMorphingV01). Using another setting by just defining the directional diffusivity: solver velocityComponentLaplacian; component x; diffusivity directional (1 0 0); spatial distribution of density, temperature and pressure looks physically reasonable but in the time evolution density does not change, hence is not corrected. Can someone help me with a simple working example, where a box is compressed using the compressibleInterDyMFoam. This would be really helpfull. I might have specified wrong bc's for the moving wall or the dynamicMesh settings are wrong. I do really not have any clou, where to search/look from my user-settings perspective. I also do not know, whether I have to activate correctPhi. | ||||
Steps To Reproduce | The here discribed behavior can be reproduced by using the case from the last bug-report: https://bugs.openfoam.org/view.php?id=2824. | ||||

I am running the case with pure air and the settings solver velocityComponentLaplacian; component x; diffusivity directional (1 0 0); and the density is uniform (apart from one corner cell) and increases as expected. Are you running with the correcties provided to compressibleInterDyMFoam? |
|
With diffusivity inverseDistance (fixedArc); I get uniform pressure, density and temperature fields except in one corner cell. |

Hi Henry, Thank you for your comment. I assumed the changes were already included in the update from 05022018, but I was wrong as I found out by checking the files. I included the correcties and everything works fine. Thank you for your work an time. I think this case can be closed. |
