Resumen de Natural cubic element formulation and infinite domain modelling for potential flow problems
G. A. Mohr, A. S. Power
A simple formulation of a 9 df cubic Hermitian finite element for potential flow problems is given, using the interpolation of the BCIZ element and after Argyris, defining natural velocities parallel to the element sides. Consistent loads for body forces are also derived and it is shown that these are necessary to obtain accurate results when body forces are significant. Example problems include those of infinite domains for which simple conditions at infinity are used.
