1. A computer-implemented method of guiding a workflow, using a computer system, the method comprising: receiving a geometric model of a patient's anatomy, the geometric model being defined by a plurality of geometric parameters; determining one or more quantities of interest associated with the patient's anatomy; determining a sensitivity value of each of the one or more quantities of interest to changes in values of the geometric parameters of one or more subdivisions of the geometric model; and generating or modifying, using a processor, a sequence or workflow of user interfaces for enabling a user to interact with the geometric model based on the sensitivity value of the each of the one or more quantities of interest.
