OK I Think you hit on a bug.
First you have a space that is not assigned to a thermal zone (Space 1 - 1) but that is not the issue.
When I tried running your model after deleting Space 1 - 1, on OS 2.5.1 I got that fatal:

```
** Severe ** CalcCoordinateTransformation: Invalid dot product, surface="FACE 39":
** ~~~ ** ( 64.008, 8.839, 0.000)
** ~~~ ** ( 64.008, 42.672, 0.000)
** ~~~ ** ( 64.008, 42.672, 0.000)
** ~~~ ** ( 64.008, 51.511, 0.000)
```

Which means that the model as overlapping vertices in surface Face 39. as you can read.
Your original OSW file doesn't have it:

```

64.008, 8.8392, 0, !- X,Y,Z Vertex 3 {m}
64.008, 51.5112, 0; !- X,Y,Z Vertex 4 {m}
```

It shows up in the in.osw generated only during simulation :

```

76.8096, 8.8392, 0; !- X,Y,Z Vertex 9 {m}
```

And then being translated into the in.idf:

```

I believe that this bug was already reported here and got to do with the geometry editor.

I was able to work ... (more)

@M 108014 have you manually deleted objects from that OSW file? Could you post a link to that model?

@Avi No, I did not delete any object manually from the OSW file. Please find attached the link to the model
