hi again,
I approached some success but still there is another error!!! :(
I remove my box from the mesh, so I have just a rectangular. instead I create the box with topoSet:
Code:
actions
(
{
name c0;
type cellSet;
action new;
source boxToCell;
sourceInfo
{
box (1 0.75 0) (2 1.25 1);
}
}
{
name c0;
type cellZoneSet;
action new;
source setToCellZone;
sourceInfo
{
set c0;
}
}
);
and create a MRFZones in constant:
Code:
1
(
cellZone c0;
{
// Fixed patches (by default they 'move' with the MRF zone)
nonRotatingPatches ();
origin origin [0 1 0 0 0 0 0] (1.5 1 0);
axis axis [0 0 0 0 0 0 0] (0 0 1);
omega omega [0 0 1 0 0 0 0] 104.72;
}
)
and the dynamicMeshDict:
Code:
dynamicFvMesh solidBodyMotionFvMesh;
motionSolverLibs ( "libfvMotionSolvers.so" );
solidBodyMotionFvMeshCoeffs
{
cellZone c0;
solidBodyMotionFunction rotatingMotion;
rotatingMotionCoeffs
{
CofG (1.5 1 0);
radialVelocity (0 0 360); // deg/s
}
}
when I ran it after some iterate the following errors appeared:
Code:

Floating point exception
when I execute the paraFoam, there was just a rectangular that at its center some meshes have been rotating which they were what I defined in topoSet. but after a little the some meshes expand and some compact. there wasn't any thing like remeshing in FLUENT!!!!
anybody knows how can I solve this problem? and how can I have a separated rotating box instead of a moving mesh that has no boundary with its surrounding fluids?
please help me.
thank you.
