Compile en été affiche des erreurs en hiver

Bonjour,

J'étudie l'isolation d'un bâtiment par double façade. J'arrive à lancer la simulation pour une semaine d'été, mais je reçois quelque 8 warning et 3642 severes pour l'hiver ou la simu annuelle.

Je reçois :

Ce cernier severe est affiché pour chaque vertex de chaque mur de chaque zone... donc beaucoup de fois.
Puis le message finit par :

************* ===== Final Error Summary =====
************* The following error categories occurred. Consider correcting or noting.
************* Interzone surfaces - different zones
************* Temperature (high) out of bounds
************* ..A temperature out of bounds problem can be caused by several things. The user should check:
************* ..1) the weather environment (including the horizontal IR from sky)
************* ..2) the level of interal gains with respect to the zone
************* ..3) the thermal properties of their materials. And other things.
************* ..A common cause is a building with no or little thermal mass - all materials with Material:NoMassdefinitions.
************* Nominally Unused Constructions
************* ..The nominally unused constructions warning is provided to alert you to potential conditions that can cause
************* ..extra time during simulation. Each construction is calculated by the algorithm indicated in the HeatBalanceAlgorithm
************* ..object. You may remove the constructions indicated (when you use the DisplayExtraWarnings option).

Pour être franc je viens de me mettre sur DB et je ne comprends pas vraiment tout ce que cela signifie. Je suppose qu'il s'agit d'une erreur que se répercute partout. La convergence du modèle peut-être ? Avez-vous une idée ?

Merci à vous

Coco

Bonjour,

Les premiers messages indiquent un problème de calcul de la quantité d'ensoleillement atteignant des surfaces. Ces erreurs ne stoppent pas le calcul mais signifient
que le flux solaire est mal pris en compte. Dans votre cas, une surface fait de l'ombre à une autre mais n'est pas prise en compte.
Ceci est du au fait que vous avez choisi la Distribution solaire intérieure et extérieure complète. E+ est limité dans son calcul à des zones convexes, si ce n'est pas le cas
il émet une erreur. Vos zones sont certainement non convexes (toutes les parois doivent se voir l'une l'autre sans passer au travers d'une autre).

Enfin, la dernière erreur qui arrête le programme est due à une divergence des calculs de température pour la cloison FDPRUE:ZONE1_PARTITION_55_0_10175 de la zone FDPRUE ZONE 1,
la température atteint plus de 5000 °C donc il y a un problème de paramétrage. Ce peut être du :

• La surface trop petite de la cloison étant donné le flux de chaleur qui l'atteint
• Elle est adiabatique et la chaleur n'arrive pas à être évacuée
• Les matériaux très inertiques provoquent cette divergence

Pour retrouver cette cloison dans votre modèle, cliquez sur les cloisons de la zone en regardant dans l'onglet Sortie > Simulation, le code E+ est affiché ici.

Cordialement,

Bonjour,

Merci d'avoir répondu. Cela marche maintenant!
