In mathematics a partial differential algebraic equation (PDAE) set is an incomplete system of partial differential equations that is closed with a set of algebraic equations. == Definition == A general PDAE is defined as: : where: * F is a set of arbitrary functions; * x is a set of independent variables; * y is a set of dependent variables for which partial derivatives are defined; and * z is a set of dependent variables for which no partial derivatives are defined. The relationship between a PDAE and a partial differential equation (PDE) is analogous to the relationship between an ordinary differential equation (ODE) and a differential algebraic equation (DAE). PDAEs of this general form are challenging to solve. Simplified forms are studied in more detail in the literature.〔Wagner, Y. 2000.
