How to find what associations nodes/curves/etc are referencing, for future deletion from the model.

How to find what associations nodes/curves/etc are referencing, for future deletion from the model.

How to find what associations nodes/curves/etc are referencing, for future deletion from the model.

(OP)
How can you easily see what associations my nodes (or any geometry/mesh features) are using? I have a set of nodes that I want to delete, but cannot. I assume they are still using an active association of some sort. Yet, when I delete just about everything from my model tree, I still can't delete these nodes.

With that said, maybe it has nothing to do with associations. What is the approach I should take if I'm having trouble deleting non-deletable nodes?

Dear Cheyne,
First at all do a "FILE > REBUILD", this will verifiy the integrity of your current active model and simply will check whether all entities that are referenced by other entities exist in your model. Next delete your mesh. If you keep having nodes undeleted this is because you have prescribed loads or constraints to that nodes, instead to the geometry, then FEMAP keeps nodes undeleted.
Best regards,
Blas.

you can't delete a node that's being used in some manner. to see if the node is connected to the model list elements using the nodes (you might make a group of these troublesome nodes). remember there are many ways to use nodes ... constraints, loads, beam reference axes, ... if they're not connected to the model, they shouldn't affect the results.

Blas and rb,

The rebuild did the trick! Should I always use this tool after any model editing, preceding an analyses run?

Before posting this thread, I tried deleting the mesh, geometry, loads, constraints, etc. belonging to the troublesome nodes, and the nodes still would not delete. A step further, I then attempted to eliminate any existence of the node's references (I used the term "associations" in my initial post) by deleting all elements, properties, materials, loads, and constraints out of my model tree (having saved my model before hand:)) just to see if they were in fact referencing and entity and could be deleted... Yet, they still could not delete. I gave up at that point, and came here... I let them be for awhile, and rb was correct in the fact that they didn't affect my results. Though, I still wasn't comfortable having these useless nodes floating in my model.

As always, you guys come through with the perfect solution!

Thanks again.
