Hola, en teste momento me encuentro tratando de hacer una simulacion de tunel de viento en Fluent, pala lo cual he realizado una malla en el Gambit y lo he exportado a un archivo .msh, luego al leer el caso con fluent y empieza a construir la malla da un mensaje que dice: Peligro: volumenes no positivos existentes. De la misma manera al dale en Malla>chequear el mensaje que arroja es: Peligro: Chequeo de malla fallado, por favor si alguien sabe por que me da este error y me pueden ayudar lo agradeceria mucho, por si acaso les dejo abajo lo que el programa muestra cuando cargo y chequeo la malla.

The default algorithm used to compute the wall

Please inspect the wall distance by displaying the
contours of the 'Cell Wall Distance' at the
boundaries. If you observe any irregularities we
recommend the use of an alternative algorithm to
correct the wall distance.
