The disclosed embodiments include systems and methods to determine the steering of a bit. The method includes receiving input parameters associated with a model of a bottomhole assembly having a housing and a shaft that runs through an interior of the housing. The method also includes analyzing the housing as a first beam, and analyzing the shaft as a second beam that is nested within the first beam. The method further includes estimating a force and moment at a contact point between the shaft and the housing, determining a housing deflection based on the force and the moment, determining a shaft deflection at the contact point, and determining whether the shaft deflection is within a threshold of the housing deflection. In response to a determination that the shaft deflection is within the threshold of the housing deflection, the method further includes providing an output indicative of steering of a bit.
