SubscriberEstoy simulando un problema simple de transferencia de calor en una tuberia. La calidad mÃnima ortogonal de mi malla es casi de 0.3, sin embargo cuando inicializo (con 10 iteraciones) me muestra este mensaje: warning: convergence tolerance of 1.000000e-06 not reached during hybrid initialization.
Cuando inicializo con las 10 iteraciones me muestra el mensaje de advertencia, pero mi solución llega a una convergencia.
Por otro lado cuando inicializo con 11 o mas iteraciones para hacer desparecer el mensaje, corro la solución y el problema llega a la convergencia.
DeberÃa ignorar el mensaje?

Ansys EmployeeHello,
Yes, you can ignore the warning message if the solution reaches convergence and if the solution is accurate.

Ansys EmployeeHi,
It suggests that the default number of iterations was not sufficient to initialize the velocity and pressure fields to the desired level of accuracy. To address this, you can increase the number of iterations in the General Settings tab of the Hybrid Initialization Dialog Box. This may be particularly necessary for complex and highly curved geometries. Â For complex and highly curved geometries, if the default number of iterations is not enough to reach the convergence tolerance of 1e-06 and the flow fields are not to your liking, then you may want to increase the number of iterations and re-initialize the flow.
For more details, please check fluent user's guide: 35.11. Hybrid Initialization (ansys.com)
Thank you

Los campos de flujo y resultados en general son precisos.Perfecto, muchas gracias por aclarar mis dudas.
