Hello,
This might be suggesting that your mesh quality is poor or your model is improperly set up. Please check the mesh quality and verify that you have a good mesh.
If yes, then provide details on how you set up your model (along with screenshots) and we will help you identify the issue.

Thank you for your reply Sir!
I'm tryin to simulate the beheviour of an external flow around a winsdor (Ahmed Body model).
My objectif is to visualise how the parameters that i want to calculate change around the vehicle,So
I have createdan outer fluid domain and inner fluid domain near to the geometry for minimise the mesh elements.
the pictures as follows shows the methods that i have used for meshing and fluid domain.
cordialment!

Could you please check the quality of your mesh, especially at the Ahmed Body? You should be able to do this in Ansys Meshing.
Click on the Mesh -> Properties -> Statistics.
Check for Orthogonal Quality & Skewness.
