I am trying to do hexa dominant mesh for that i have splitted a body and used a shared topology option , but whenever i use shared topology instead of Contact it doesnt create the mesh. Multizone option does work when i keep hexa core as setting. What can be possible reason everytimes this happens. I feel the share topology option create some imprint on the geometry will that be Reason or something else?

Hello Bala,

What are the error messages generated by the solver? Here’s a simple geometry I tried to mesh without and with shared topology respectively:

Shared topology merges the pair(s) of common faces between bodies into a single set of common faces (2 faces become 1 face). The shared faces belong to both of the neighboring bodies. When meshing these types of multibody parts, the mesh at the interface will be conformal. When I hide the cylindrical bar, we can see how mesh transforms to match with other body nodes:

Here’s an Ansys help link, which will give more information on how shared topology works:

Thanks for the reply. here , in the first pic the hexa dominant mesh cretaed on both componnents but when you used shared toplogy it didnt make hexa mesh on one component, I want both compnent meshed in hexa that is happening in my case. I am getting some error like match face is not found etc. 

 

Aslo why I am not able to accsess the conformal meshing link that you have shared.

Hello Bala,

For the same model, using shared topology, the solver by default generates tets. But when I force it to "Hex dominant", I face no issues here. Here are the screenshots:
