We discuss various algorithms that one can use in conjunction with Lagrangian methods for the treatment of important deformation of the mesh. We develop a new contact algorithm. The free fall of a droplet of fluid in a light gas serves to illustrate the potentialities of these techniques.
Résumé
Nous étudions un problème modèle de chute libre d'une goutte de fluide dans de l'air à l'aide de méthodes numériques lagrangiennes. Nous développons et étudions un nouvel algorithme de contact qui permet (numériquement) à la goutte de toucher le sol.
