Dynamic mesh settings in Fluent for Two-Way FSI
I have some questions regarding remeshing settings for two way FSI.
I am analyzing a turbulent flow for which I follow the minimum and maximum length scales information for setting the respective parameters. When I used a higher value for maximum length scale i.e. around 0.05 (m) it gives a coarser mesh around the structure after deformation. Then I changed this value to some lower value around 0.001 (m), the mesh around the structure becomes finer but it does not give the consistency in results for different flow velocities. For example : for the lower velocity case the deformation of the structure exceeding to that in highest velocity.
I don not change the other simulation parameters, is the difference in results is because of these remeshing scales?
Moreover there is also difference in results for the new remeshing scale (Max length scale: 0.001m ) as compared to the previous value (0.05 m).
Could any one please help me about this?
