Abstract
In this paper we show that falling friction poses a principal difficulty for the FASTSIM algorithm. Using velocity-dependent μ leads to discontinuities in the tractions, displacements and slip velocity. These discontinuities are due to the local and instantaneous relations that are used. They are circumvented in different, unsatisfactory ways in the extensions of FASTSIM that are presented in the literature. We describe a new FASTSIM algorithm that deals with falling friction properly, using the concept of friction memory.
