Bonjour
je vous remercie pour vos aide. lors de l'exécution de ce code avec gfortran je rencontre le problème suivant

heartliddrivchannel.for:99.29:

      call gbound(g,theta_in,Y,w,n,m)                                   
                             1
Warning: Rank mismatch in argument 'y' at (1) (rank-1 and scalar)
heartliddrivchannel.for:104.32:

      call result(u,v,rho,theta,Y,uo,n,m)                               
                                1
Warning: Rank mismatch in argument 'y' at (1) (rank-1 and scalar

Qu'est ce que je peut faire?
est ca pose un probleme dans l'enregistrement de fichier dat?
merci bien

Bonjour,

La variable Y n'étant pas déclarée dans le programme principal comme un tableau de réels, elle est considérée comme un réel simple (typage implicite) lors de l'appel de la subroutine gbound, ce qui est à l'origine des avertissements. Il suffit de rajouter la déclaration dans la liste des déclaration du programme principal.
Code:

1 2 3 4 5 ! declaration de variables parameter (n=1000,m=50) real Y(0:m) ...

probleme de stokage de resultats

Bonjour
j'essaye toujours de resoudre le probleme de simulation d'un ecoulement dans un canal en determinant la vitesse et la temperature. le probleme dans mon code et que la vitesse ainsi que la temperature sont nulles. malheuresement je rencontre aussi un probleme avec le stokage de resultat pour le fichier 6 qui enregistre les lignes de courants enregistre aussi le contenu du fichier 7 et lorsque je demande un affichage sur l'ecran j'nobtient rien mais tous dans le fichier 6.
merci bien pour vos temps precieux que vous le me consacrez. je compt beaucoup sur vos soutien et vos comprehension.merci bien merci

Il vaut mieux commencer la numérotation des unités de fichier à partir de 10.
L'unité 6 par exemple correspond à la sortie vers l'écran. D'où le problème.
Ouvrir 9 fichiers en même temps n'est pas une bonne pratique non plus.
