Hi All,

I wrote a couple of equations for scaling my domain. Its a 2-D damper( two circles,the inner one with eccentricity). Since the domain was small, I was trying to scale it radially by coordinate transformation.

{theta} = atan(abs(({Y}/{X})))
{R} = sqrt({X}**2+{Y}**2)-0.0632
{i2} = cos({theta})
{i3} = sin({theta})
{sY} = sign({Y})
{sX} = sign({X})
{A}={R}*{i2}*{sX}
{B}={R}*{i3}*{sY}

But the issue is for a constant reduction in the value of R, the domain thickness will not change.

Thanks in Advance.
