A diversity of earthquake research relies on incorporating existing, but relatively sophisticated, renderings of 3D fault geometry into the corresponding analytical models and numerical simulations. For instance, geodetic creep rates of faults are estimated via surface deformation observations and 3D finite fault models, while dynamic simulations of earthquake rupture precondition complex fault geometry as boundary conditions. Emerging geostatistical analyses are integrating seismicity patterns, earthquake geology, and probabilities to refine community fault models (CFM) intended for an array of scientific investigations. We develop an on-demand framework, CFM Remesher, to allow non-modeling-specialized users to modify any fault meshes within the latest CFMv6.1. Through the CFM Remesher, users are able to request different mesh sizes/types and fault-top/bottom depths that better fit into the requirement of their scientific research. Eventually, this effort is to promote the usage of CFM allow more impromptu earthquake researches taking advantage of structural complexities mapped in California
