# Patch Missing Adjacency

Set any Faces of Rooms with missing adjacencies to Adiabatic.

This is useful when simulating a subset of Rooms from a larger Model.

If any of the Faces with missing adjacencies have sub-faces, these will be removed in order to accommodate the adiabatic condition. Similarly, if the Face is an AirBoundary, the type will be set to a Wall.

### Inputs

* **rooms \[Required]**

A list of Honeybee Rooms which will have its adjacencies patched with Adiabatic boundary conditions. This can also be an entire honyebee Model. Any adjacnecy not found across all of the rooms will be replaced with an Adiabatic boundary.

### Outputs

* **rooms**

Rooms that have had their missing adjacencies patched.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://docs.ladybug.tools/hb-energy-primer/components/0_basicproperties/patch_missing_adjacency.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
