Ignor&eacute; este mensaje y segu&iacute; trabajando, pero cuando intento inicializar, la consola me muestra un mensaje de error y no me permite simular.&lt;br&gt;Estoy anexando im&aacute;genes de los errores que me muestra Ansys Fluent, as&iacute; tambi&eacute;n de mi malla generada.. Cabe resaltar que intent&eacute; realizar el mismo trabajo, bajo las mismas condiciones de contorno en un tubo de venturi 3D y Ansys no me muestra tal error.
