This ends up costing the customer a lot of time remaking their part simply running the diagnostic tool in the beginning would have saved a lot of headaches. There are many times where I have seen customers import their geometry, start adding features, and then when they start to have problems, we find that their initial geometry was faulty. If you use imported geometry (IGES, STEP, Parasolid, etc.), this tool is something you should already be familiar with. This tool can be found in your Evaluate tab on the Command Manager, or under Tools > Interference Detection (at the Assembly level). Having this checkbox on will list, in addition to any material interferences, all sets of touching faces.Īlso, a checkbox that should be on is the “Include multibody part interferences” (don’t want to forget those).
This is where the “Treat coincidence as interference” checkbox comes in. Flow Simulation is not as concerned with interference, but if you are doing heat conduction problems, it’s very important that the faces that you think are touching, are actually touching. Interference detection is a very useful tool found in your Evaluate tab on the Command Manager, or under Tools > Interference Detection (at the Assembly level). This tool can be found with the Flow Simulation add-in turned on under Flow Simulation > Tools > Check Geometry. This tool will also check if you have a fully enclosed fluid volume, something you are going to need if you are doing an internal analysis. Certain invalid contacts can be fixed by this tool, but it is a good idea to fix these yourself before proceeding any further. This is a great way to find out if you have any invalid contacts that Flow Simulation doesn’t like.
