Dear Community,

I have a model of a room, meshed in GAMBIT as a *.dbs-file, in binary format.

Now I want to insert a cylinder. The nodes and the connectivity are available in 3 different formats to chose from , see underneath.

Is this feasible ?

We have no access to GAMBIT any longer. We do have the following modules from ANSYS : Fluent, Design Modeler, Space Claim, Workbench; all in the release 19.2.

The cylinder nodes and connectivity should be preserved after insertion. Can a conflict between identical node or element numbers between the dbs-file and the file for the cylinder be avoided automatically ? Alternatively, I could add a fixed number to all node and element numbers of the cylinder.

Your expertise is highly appreciated.

Sincerely

FrankR
