The term “p-extension” refers to the process of systematically and hierarchically increasing the polynomial order of the element shape functions on a fixed mesh, thereby increasing simulation degrees of freedom (DOF) and representing more complex displacement fields for the mesh. Conversely, traditional FEA implementations require successive mesh refinements on elements of fixed polynomials, or h-extensions, […]
