Elementos fluidos en 2D y 3D para análisis dinámico con interacción fluido-estructura

Abstract

Se presenta un elemeto finito, formulado en desplazamientos, para análisis de interacción fluído-estructura, incluso en el caso de fluído con superficie libre. Dicha formulación requiere, para su buen comportamiento, el conjugarla con integración reducida, lo que en principio conduce a inatrices de rigidez deficientes en rango. Se deduce una componente de la rigidez, que es función de la posición y a la que se denoinina, por tanto, geoinétrica, que al tiempo que elimina la deficiencia en rango, perinite obtener inodos de oleaje (de baja frecuencia), a volumen constante. Ea formulación obtenida se generaliza a 3D donde es preciso eliminar modos espureos adicionales, penalizando no sólo las rotaciones, como en 2D, sino también sus derivadas espaciales, es decir, las componentes de la torsión.
