Low-speed preconditioning
 
Hello,

This question is manly for Edge developers:
I was looking a bit at the low speed preconditioner.
Does anyone know if the rotating reference frame was taken into account when constructing the preconditioning?

In the previous releases (3.3) a bit different preconditioner was used (i hope so) and both absolute and relative velocities were used to construct all the transformation matrices, while in the new Edge releases the matrices are constructed only from absolute velocities (at this point I became a bit suspicious).

Can anybody recommend a book/paper/etc. on preconditioning (related to the methods used in Edge, if possible)?

Thank you,
Ales

I think I found some solution and sources...

I think it is, not 100%, would have to go to the source code.
Seems you've already figured it out though
