I am modeling a helical pipe encased in a solid medium (backfill). The medium is surrounded by soil. The pipe has water inside.
I created a hollow pipe and then imported it to Ansys (SpaceClaim). I then created a cylinder surrounding this pipe and used the merge command to get a cylindrical backfill around this pipe and water (body inside the helical pipe). The backfill is surrounded by cylindrical region of soil.
When I import the model for meshing, multiple contacts are automatically generated. Most of these have unequal number of target to contact faces e.g. Contact 2 has 6 contact faces and 8 target faces. In addition they form overlapping contacts that need to be repaired.
I wanted to avoid these so I decreased the tolerance value of the auto detection in details of contact. I then get lesser contacts but some still need to repair and suppress some.
Once I repair them and import the Mesh to Fluent I get this error message:
Warning: zone of type interior found between different solids!
Material of cell zone 7 is bckfill, while material of cell zone 8 is hdpe.
Warning: zone of type interior found between different solids!
Material of cell zone 7 is bckfill, while material of cell zone 6 is soil.
This will adversely affect the solution.
It is recommended that you fix this issue via the TUI command

You can use "Share Topology" in SpaceClaim to get the contacts right in the Geometry already.
