Hi, everyone.
I'm a newer to OpenFoam. I want to simulate the flow of one rotating disk in the cavity with inlet and outlet. Firstly, the simulation using icoFoam solver with laminar nonrotating case is ok .
But when I give the rotating speed by using the rotatingWallVelocity, the code doesn't work. The error is "Floating point exception" .
I think it should not be due to the mesh, because I can get the results with ANSYS Fluent.

Here's my code. Can anyone give me some advices?
::::::::::::::::: file::::::::::::::::::::::::
dimensions [0 2 -2 0 0 0 0];

internalField uniform 0;

boundaryField
{
INLET
{
type zeroGradient;
}
OUTLET
{
type fixedValue;
value $internalField;
}
ROTOR
{
type zeroGradient;
}

STATOR
{
type zeroGradient;
}
}

::::::::::::::::::U file::::::::::::::::::::::::
dimensions [0 1 -1 0 0 0 0];

internalField uniform (0 0 0);

boundaryField
{
INLET
{
type fixedValue;
value uniform (-0.283 0 0);
}
OUTLET
{
type zeroGradient;
}

ROTOR
{
type rotatingWallVelocity;
origin (0 0 0);
axis (1 0 0);
omega 262;
}

STATOR
{
type noSlip;
}
}
