Re: [SOLVED] PRE_SIGM use for Preload

je n'ai pas d'exemple simple précis sous la main
peut être le post  id=20524
en gros il s'agit de suspendre le ou les objets à quelques points fixes dans l'espace avec des ressorts (éléments K_T_D_L) suffisamment souples pour ne pas polluer le résultat et bloquer les mouvements de corps rigides
un petit peu d'essai et erreur ici
ces éléments sont a crées dans la géométrie, à mailler (1 seul élément sur la longueur) et doivent être affectés dans le modèle
