Numerical tools for efficient simulations of such drilling applications are explained. We model the fluid flow with the Navier-Stokes equation in a rotational frame of reference and the solid domain is treated with the Fictitious Boundary Method (FBM). This enables us to utilize a unified mesh for the solid and fluid part of the domain and heat transfer between these is treated in an implicit way.enErgebnisberichte des Instituts für Angewandte Mathematik;651drilling simulationfictitious boundary methoddiscontinuous drillingFEMCFD610preprint
