P Method Finite Element
P Method Finite Element. Similar to the thermal energy conservation referenced above, it is possible to derive the equations for the conservation of momentum and mass that form the basis for fluid dynamics. The finite element method is exactly this type of method - a numerical method for the solution of PDEs.
The key is to understand that the finite element method can only solve this type of equation. Thus, it strongly supports the analysis of problems with highly complicated geometry. This is the way I understood that: There's a weak formulation of the finite element.
Many successful numerical methods for dierential equations, including the nite element method, aim at approximating the unknown function by a sum.
Example on piecewise cubic finite element basis functions.
The ALE formulation has being used in conjunction with stabilized finite element method to derive a number of numerical procedures for fluid-structure interaction (FSI) analysis. The solution approach is based either on eliminating the differential equation completely (steady state problems). The key is to understand that the finite element method can only solve this type of equation.
