1. An apparatus for execution of a computer-based model, the apparatus comprising:
machine-readable instructions;
at least one processor circuit to execute the machine-readable instructions to:
prior to execution of the computer-based model, identify a donor and a recipient representative of one or more model regions of the computer-based model to simulate for a plurality of time steps including a first time step and a second time step, the donor having donor properties and a first model component, the recipient having recipient properties and a second model component;
in response to computing a flow field for the first time step of the computer-based model, extract the donor properties from an extraction surface of the donor;
generate a boundary condition at the extraction surface based on the donor properties;
replace at least one of the second model component or the recipient properties with the boundary condition;
and
generate an output flow field for the second time step based on a simulation of the second model component with the boundary condition.
