Hi Bruno,

Actually, I'm doing research on wind-wave interaction. I'm a graduate student of wind engineering, my final goal is to study mean wind profiles over the ocean under strong wind and give...

Bug lies in waveDisplacement due to update the internalFields alone without other BCs

Hi Bruno,

Thank you for the quick reply and good advice!

I'll make a report to the bug centre later. I guess it is not a problem with the cyclicAMI BC, for when I replace 'cyclic'...

Mesh goes into a mess with cyclicAMI

Hi Bruno,
Thank you for the supplement!

I tried cyclicAMI for my case, and found the mesh intersects using cyclicAMI which will not happen with cyclic.

Attacted are my cyclic and cyclicAMI...

I'm now more sure about the existence of bugs, since it runs well in parallel mode with the same BCs(2 pair of cyclics,i.e. channel395 case) for static mesh and runs well in serial mode but crashes...

I guess there must be something wrong with the updatecoeffs() in the source code of e.g. oscillatingDisplacement. So when running in parallel one processor updated the coordinates and set the switch...

parallel running error with cyclic BCs for pimpleDyMFoam

Problem remains unsolved, here is the case file, hope anyone can check it and give some help!
Just run the following applications:
blockMesh
decomposePar
mpirun -np 2 pimpleDyMFoam -parallel

I think serial run is running with several cores one after another rather than parallel, so I run "mpirun -np 2 channelFoam (here -parallel is removed so that it becomes serial mode)". But I think...

What is serial mode? I'v never heard of that before, could you explain a little bit? And is it ok to replace cyclic bc with cyclicAMI since the latter stands for cyclic arbitrary moving interface?...

parallel error with cyclic BCs for pimpleDyMFoam and trouble in resuming running

Two problems found when using pimpleDyMFoam and waveDisplacement：

1. When I use pimpleDyMFoam together with cyclic boundary conditions,(actually I use waveDisplacement, you can try the...
