Accessing Vulcan
Vulcan can be accessed from https://usevulcan.app/launch
Vulcan works with files stored locally on your device. For the full local workspace workflow, use a Chromium-based browser such as Chrome or Edge. Vulcan can be used on Windows or Mac.
You will be asked to choose a local workspace folder. This is where Vulcan stores modelling inputs, output files, overlays, SAP files, and related supporting files.
On-device storage gives you direct access to your work, but also means you should take care when storing files. We recommend using a secure device, enabling multi-factor authentication where available, and regularly backing up your workspace.
Logging in to Vulcan
You can log in to Vulcan either from the website (https://usevulcan.app/auth) or directly from the web app (https://usevulcan.app/launch).
We recommend using your email and password to log in to Vulcan at this time, and using a secure password manager so you can set a strong password. If required, you can also reset your password or use a "magic link" that only requires your email and access to your email account.
Please reach out via our in-app support chat if you have questions using Vulcan.
User workspace and input/output files
Vulcan stores files locally. After every login, you will have the option to choose the workspace where these files are stored. If you close the Workspace menu, or want to change the workspace, you can access it again via the Settings button on the top right of the app screen. This also contains menus for integrations, licensing information, and your profile page (also accessible at https://usevulcan.app/profile).
In your workspace, the most important folders are:
input/base_models - geometry CSV files created from the Geometry section.
input/batch_parameters/base_json - complete HEM input files created when geometry is merged with defaults.
input/batch_configs - scenario configurations created in the Scenarios section.
input/batch_parameters - the parameter library and any parameter snippets you create or edit.
input/analytics - metric definitions used in the Results section.
input/tariff_data_structured - tariff files used for cost metrics in Results.
input/sap - uploaded SAP PDF/XML files and extracted data used for comparison.
input/overlays - uploaded floorplan overlays.
output - simulation outputs from the Scenarios section.
logs - temporary logs created during local modelling workflows.
You do not normally need to create these folders manually. If you are unsure, open or refresh the workspace from inside Vulcan.
Sample Parameter Library
The Sample Parameter Library installs a set of useful example files into input/batch_parameters. These provide defaults, weather files, system examples, fabric assumptions, model wrappers, and other parameters used by Scenarios and Results.
Install or restore the library from the workspace menu. If the library is missing or out of date, Vulcan may not be able to run normal scenario workflows correctly.
