This page links to the main Vulcan user guides.

Setting up: Logging in, setting up the workspace, getting support

Geometry: Entry of dwelling inputs and selection of a defaults file

Fabric calculators reference: How assembly, ground-floor U-value, and unheated-space thermal resistance calculators work (standards, formulas, defaults)

Calculate: Selection of inputs, attaching evidence, and viewing results

Scenarios: Defining batch model parameters and running simulations

Results: Aggregating and visualising metrics from output files

Vulcan also includes some experimental functionality. These features should be used with caution and outputs should be checked carefully:

Create SAP XML: In Scenarios, users can toggle creation of a SAP10 XML. This functionality is still in development, and has not yet been run with official SAP test cases.

MCP server: Use selected Vulcan functions directly with local scripts or agents. This can be accessed via the Integrations menu in the Profile dropdown.

IFC file imports: Use files from CAD tools within Vulcan. This is an option in the Files dropdown in the Build Geometry tab.
