Claim:
1. A method comprising: inputting at least one wellbore fluid property, at least one wellbore condition relating to a section of a wellbore, and at least one operational parameter into a computational method, wherein the computational method is configured to analyze sag within a section of a wellbore, and wherein the wellbore fluid property relates to a wellbore fluid that comprises a weighting agent; producing a sag profile of the section of the wellbore with the computational model, wherein producing the sag profile involves: meshing the section of the wellbore into a plurality of elements and performing a mass balance analysis on each of the elements for each component in the wellbore fluid; and performing a wellbore operation with at least one of a second operational parameter, a second wellbore fluid parameter, and a second wellbore condition based on the sag profile.
