Hi,
in order to improve the mesh quality for a fluent compressible flow simulation i was thinking about slicing up a body into several bodies and meshing each component individually, and reconnecting them via mesh interfaces.
By doing this i could improve the mesh quality and micro-manage the mesh generation.
I wanted to know if this is generally a good idea and what kind of precautions i would have to take and what else i would have to take care of.
I am happy for any pointers or help.

Hi,

Could you please share with us your bodies? you know that you could simply assemble your geometry that has a variety type of bodies.Then you could see that geometry you have defined have been shown like one-by-one parts in DesignModeller.

As for Ansys-Meshing, you could hide any parts (or supress) and make it mesh you would like to

After some mesh operations complete, you could see in mesh metric what it is like for example skewness must be max 0.95, orthogonal quality min is approximately 0.1 .Then you have to look at element quality in mesh-metric.Maybe some locations you will see would be not enough then mesh relevant locations

Kind Regards,

hi oozcan,
thank you very much for your reply. The reason for me using the separate body approach is reducing skewness and improving orth. quality. This way i get quality meshes on each distinct body. My post was targeting the question if this approach is in general sensible.
