Methods for analyzing sag in a section of a wellbore may utilize computational methods that produce sag profiles, which may be useful in performing further wellbore operations. The computational method may include inputs of at least one wellbore fluid property, at least one wellbore condition relating to a section of a wellbore, at least one operational parameter into a computational method, and any combination thereof. Further, the computational methods may include a mass balance analysis for individual elements of the meshed section of the wellbore.
