FSI motion error
1 Attachment(s)
Grids of my 3D geometry are leaving some gap at interface between solid and fluid.[see- attachment]
What could be the reasons for it?
solver- icoFSIElasticNonLinULSolidFoam
motion U
Code:
FoamFile
{
version 2.0;
format ascii;
class tetPointVectorField;
object motionU;
}
// * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * //
dimensions [0 1 -1 0 0 0 0];
internalField uniform (0 0 0);
boundaryField
{
plate
{
type fixedValue;
value uniform (0 0 0);
}
topWall
{
type slip;
value uniform (0 0 0);
}
bottomWall
{
type fixedValue;
value uniform (0 0 0);
}
outlet
{
type fixedValue;
value uniform (0 0 0);
}
frontAndBackPlanes
{
type slip;
value uniform (0 0 0);
}
inlet
{
type fixedValue;
value uniform (0 0 0);
}
}
U
Code:
FoamFile
{
version 2.0;
format ascii;
class volVectorField;
object U;
}
// * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * //

}

value uniform (0 0 0);
}

value uniform (0 0 0);
}

}
inlet
{
type transitionalParabolicVelocity;
maxValue 0.056;
n ( 1 0 0 );

value uniform (0 0 0);
}

}
}
Please help
Thanks
