From which data is your model imported?

Looking at the engine, it says facet. This means we got a faced-based geometry.

If you would check for overlaps with the power tools

Cubit will print a message with

ERROR: Currently, Cubit is unable to determine overlap for Facet-based geometry.

That doesn’t get us nowhere. so how are we sure that it’s really overlapping?

consider this short example

```
reset
create brick x 1
create brick x 1
move vol 1 x 1
find overlap
```

`find overlap`

will tell us that surface 4 and 12 are overlapping. looking at it with the powertools it will say, that there is no problem. doing

```
intersect vol all
```

will end up with

so it is actually not really overlapping, more like it’s already touching but not penetrating.

so how does it look if we really overlap?

```
reset
create brick x 1
create brick x 1
move vol 1 x 0.9999
find overlap
```

`find overlap`

will tell us surface 4 and 12 overlap. same as before. looking with the powertools already tells us there is a problem

that’s unfortunately not an option in your case.

```
intersect vol all
```

will in fact create us a new volume. because it’s really overlapping.

as you’ve got a pretty complicated model here. there are two options.

• getting an acis model imported in cubit, so we can use the power tools

• sort out the overlapping pairs from `find overlap`

with for example `intersect vol 13 2176`

`intersect vol 13 2176`

will produce a null intersection. so it’s not a overlap pair to worry about. when that’s done we can look how to actually solve the real overlaps
