Hi,

I am trying to match nodes along the interface between a RHS and its baseplate. When the mesh uses Tetrahedrons i can simply use the Contact Match command but this will not work for Hexa mesh.

Hello Micheal I am new to Ansys, so probably you would have already tried whatever I am going to suggest. Those parts being in contact, have you tried shared topology in Space-claim ? Or is it same as Contact match command ? Sorry if this comment was not useful.

Hi Chinmay Thanks for your response.
Originally the two solids were imported from spaceclaim as a single solid, but to facilitate the use of Solid185 i had to slice the solid in the design modeller, thus creating the separate solid parts for meshing.
Based on this i dont think this will work

I was just wondering if either of you could assist me with this meshing issue.
Thanks Michael

After Slicing in DM, you should select all the solids that used to be a single part in the Outline and right click then select Form New Part. That will create a multi-body Part that will have Shared Topology automatically applied and the mesher will put shared nodes on the shared surfaces. You may need to do more slicing, such as the outer faces of the tube to get the wall of the tube to share faces with the flange. I have found slicing is faster in SpaceClaim where it is called Split Body, because you can use faces and not planes. In SpaceClaim, you then put all the solid parts in a single New Component, then Open that Component in its own window. On the Workbench tab, click the Share button to create Shared Topology.

Your a gentleman that worked a treat, thank you so much. I include snippet of the mesh now showing the link between the rhs and baseplate, i have hidden the left side and the linking nodes are more evident here as circeld in red.

I used the design modeler to rectify the problem. Regardin the slicing in the design modeller surfaces can be used for slicing as shown in the image below.

Thanks again Best Regards Michael
