Process Kernels#

Process Kernels, or PKs, are the fundamental unit of a model, and represent a single or system of Partial Differential Equations (PDEs) or Differential Algebraic Equations (DAEs). PKs are broadly split into individual equations, called Physical PKs, and systems of equations, called Multi-Process Coordinators (MPCs).

The PK tree forms the fundamental definition of the entire system of equations to be solved by the simulator, and is represented by a single PK or a single MPC which couples other MPCs and/or Physical PKs.
