CFD Online Discussion Forums - ANSA Mesh to fluent error

Hello
I am new to ANSA software
I have meshed a wing for CFD several times
When I do the mesh without layers, there is no problem to import the mesh into the Fluent
But when I use layer for mesh
I get the following error :

Code:

Ansys.Fluent.Cortex.CortexCommandFailedException: An error occured in FLUENT while applying case and settings informatins.

An error occured in FLUENT while applying case and settings informatins.

   at Ansys.Fluent.Cortex.CortexCommunicator.SendMessage(String msg, String msgKey, String errorMessage, Boolean waitForReply)

   at Ansys.Fluent.FluentCommunicator.UpdateSetupInfo(Dictionary`2 info)

   at Ansys.Fluent.Data.SetupData.ReadCaseModelInfo(IFullContext context)

any one can explain how to meshing wing and boundary volume with layers correctly
