Points on surfaces in a rotating mesh

Martin

I am looking at local heat transfer coefficients on the rotor of an electrical machine . I have two meshes with the grid interface in between them. I have been using mostly MRF model for its speed, but also Sliding Mesh several times. But Sliding Mesh allows me only to obtain average heat transfer coefficients for whole surfaces . When I define points on the rotor to obtain local values, it works only with MRF, where the rotor mesh doesn't move. As soon as first time step is carried out in SM model, all defined points become useless, as they are not on the surfaces anymore. Anyone knows how to keep the points rotating with the rotor mesh?
