Method for simulating the effect of plugs on cement placement

A wellbore servicing method comprising:

• transporting a pump unit to a wellsite having a wellbore penetrating a subterranean formation, wherein the pump unit comprises a unit controller configured to control pumping equipment to pump a treatment fluid into the wellbore, and wherein the unit controller comprises a processor and a memory;
• executing, by the unit controller, a design process is comprising:
• generating, using a computational fluid dynamics (CFD) model, a static mesh representative of a geometry of an oilfield tubular disposed within the wellbore, wherein the model receives inputs from a set of drilling data from the wellsite;
• determining, using the CFD model, a location of a geometric representation of a wiper plug within the static mesh;
• transforming, using the CFD model, a portion of the static mesh into flexible mesh cells in response to the geometric representation of the wiper plug entering the portion of the static mesh;
• and
• generating, using the CFD model, a predicted concentration of the treatment fluid in response to the geometric representation of the wiper plug reaching a target location within the static mesh;
• generating, by the unit controller, based on a result of the design process, a working pump schedule for pumping one or more volumes of the treatment fluid into the wellbore in response to the predicted concentration exceeding a threshold value at the target location;
• and
• controlling, by the unit controller, the pumping equipment to pump the treatment fluid into the wellbore in accordance with the working pump schedule.
