I am working in normal flow through the pipe for that. I am meshing it in snappyHexMesh. the checkMesh is showing that mesh is okay. But after solving it in pimpleFoam it shows a pressure discontinuity around the junction of two patches( lobe and wall).
Total 3 patches : 1. inlet 2. body(wall) 3. lobe(outlet) pressure: inlet---> fixedValue 0 ; body ----> zeroGradient ; lobe ---> zeroGradient; Velocity: inlet---> zeroGradient ; body ----> noSlip; lobe ---> fixedValue (0 0 0.001024); Here I am attaching snappyHexMesh, pressure contour, and case file.snappy.png pressure.png https://drive.google.com/file/d/1UzC...ew?usp=sharing can anyone suggest what I should do to solve this pressure issue? Thanks . Note: when I am using Ansys meshing, this problem gets solved. I noticed This pressure discontinuity is happening between two zeroGradient pressure BC. |
