The main difference between petrophysical modeling and simulation is that the former is a static representation of the reservoir, while the latter is a dynamic representation of the reservoir.

Software that uses CAD designs, digital twins, and simulation models may share all of these aspects, depending on their function, although often a specific tool will create and manipulate a model.

All of these components of a simulation have associated models. I/O buffer models include IBIS, Spice, and VHDL-AMS. Package and S-parameter models are usually in Spice or S-parameter format.

Several classes of models are used to simulate turbulence, such as direct numerical simulation (DNS), large eddy simulation (LES) and Reynolds-average Navier-Stokes (RANS) models. Different turbulence ...
