Problem with p_rgh with interDyMFoam in a ship roll decay test
2 Attachment(s)
Hi everyone. I'm trying to carry out a simulation of a Roll decay test of a ship in OpenFoam 2.1.1. I've modified the floatingObject tutorial, using snappyHexMesh to implement the ship's hull.
When I start the simulation the p-rgh field seems like this Attachment 15352 but quickly, at time 0.001, it seems like the next image Attachment 15353 There's a strange lack of pressure at the bottom of the ship, which comes with a very strong pitch movement. The COG linear velocity in Z axis rises about 1 m/s in 0.005 seconds. I've tried many different meshes, bigger and smaller, with more or less cells, but the problem is still here. Please help me, I need to carry out this simulation, it's part of a very important project. Thank you very much in advance. |
Hi Juan,
Please see the following discussion on forum regarding p_rgh: http://www.cfd-online.com/Forums/ope...urrents-7.html May be you find some relevant information. |
