 May 4, 2012, 07:29 probleme of convergence #1 New Member   sami latreche Join Date: Mar 2012 Posts: 5 Rep Power: 13 I treat the phenomenon of natural convection double diffusion for a mixture of air-h2o and air-co2 in a square cavity for a number of Ra = 10 ^ 5 then L (length caractristique) = 0.3 m the problem is: the convergence in Fluent ! the programe rest calculated ... then I think the problem is caused by the mesh I tried several meshes but same result please help me I use GAMBIT as a programe of Geometry ************************************************** ***** Je traite le phénomène de la convection naturelle double diffusion pour un mélange air-h2o et air-co2 dans un cavité carré pour un nombre de Ra = 10^5 donc L (longeur caractristique) = 0.3 m le problème est : la convergence dans Fluent ! le programe reste calcule... alors Je pense que le problème est dû à le maillage J'ai essayé plusieurs maillages mais toujour meme résultat J'ai utilisé GAMBITE comme un programe de géométrie s.v.p aidez moi
