Could anyone suggest some hints or tips to resolve "general boolean failure" when applying share topology in Design Modeller. Aside from identifying the component, what modifications / features added can be applied to achieve shared topology?

One of the main reasons in failure is geometry errors. Please check geometry in SpaceClaim or DM. Select geometry in structure tree --> Use right click --> Select Check Geometry. The geometry should be error free to proceed. If geometry has any errors, please modify/recreate geometry at those places. (Or Tools - Fault Detection in DM)

 

Another reason is having some tangential contacts at some circular surfaces. Please make sure that bodies are intersecting instead of just touching each other.

 

Sometimes bodies are in contact only at some edges. At this point volume extraction may fail. In this case as well please make sure that bodies are intersecting each other.

Thank you Keyur

I've applied fault detection and found 0 faults but after some exploring I found the following misalignment (image below). This is from a direct boolean operation in Design Modeller. This is carried over to fluent meshing and share topo in fluent meshing (join and intersect) also struggling with it. Is there any way to avoid this boolean error in Design Modeller?

Share topo should be successful in DM before proceeding to Fluent Meshing. Please work on your geometry. You may need to delete and recrete few faces/bodies. 

Please go through help manual for more details
