I am working on developing a mesh for a Fluent simulation. I have attached a picture below and as can be seen the surface mesh seems pretty uniform however, I am new to CFD and am curious if the inner mesh looks acceptable? It seems rather messy to my beginners eye. Additionally, I would really like to make the inner region of the column mesh finer compared to the outer region, is that possible?

I tried this and am still having the same issue. The only time it will run is when I have the patch conforming on but then the inflation is not doing anything.

Does your geometry consist of multiple cylinders?

Insert sweep mesh method for the body and select inflation scoped face as a 'Source' face in the mesh method.

You can also use Multizone+Inflation to create a good quality mesh. Look at the attached video tutorial for reference.
If you can provide a cross-sectional view (XY or ZY planes) of your geometry, we would be able to guide you better.

Again I am trying to make the core of this column's mesh finer. Is there a way to do that? All I can find is how inflation is used to make the mesh directly below the surface finer and this doesn't help me.

You can select surfaces in mesh and right-click to add a local sizing. I'd also look at the shape and decide if all of the features are needed as you need to resolve anything you include in the model to see their effect on the flow.

Is it possible to local size changes within the mesh and not just on the surface?

Yes, but you'd need to split a volume out to do this (or use a Body of Influence). Read up on volume decomposition.

can you suggest sources to get proper knowledge on meshing

Harish, this discussion is marked as Solved. Please post a New Discussion to ask questions. Did you try looking in the Tutorials listed in the site categories?
