[aspect-devel] cylindrical rigid body rotation

The method used in citcom is described in Zhong et al 2008 (G^3), section 2.4.1.

I wonder if there is some need for eliminating the rotational modes in
a sublayer instead of the whole geometry (as described at the end of
that section).

Yes, for sure.
