Getting Started

Five steps, about a minute of reading, to see BriskFyr build and solve a mechanism. Each step links to a tutorial if you want the full explanation — this page is the fast path.

1. Create a free account

BriskFyr's free tier is account-gated (it's what keeps compute costs sane and lets you come back to a saved project) — sign up, confirm your email, and you're in the workspace.

2. Add a Node and a Rigid Body

Build ▸ Node places a point in space; Build ▸ Rigid Body attaches a mass to it. That's a complete, solvable model — a body in free fall.

Tutorial 1 covers the whole workspace this way

3. Constrain or load it

A bare body just falls. Add a joint (Revolute, Prismatic, Spherical…) to turn it into a mechanism, or a Force/Torque/Spring to push, twist or restrain it.

Tutorial 2 builds your first joint — a pendulum

4. Solve

Solve ▸ Run sends the model to managed compute and streams progress back live. A small model (a body, a joint or two) typically solves in seconds.

5. Play back and measure

Results come back as an animation you can scrub with the playback bar. Add a Request (Distance, Velocity, Angle…) to read an exact number at any frame, instead of judging motion by eye.

Tutorial 6 covers Markers & Requests

Your work is saved automatically

There's no separate "save" step. The first time you solve, BriskFyr creates a project for your model (find it under My Projects), and every run is saved under it — so you can reopen, replay, rename or pin any run later. Loading a demo or starting a New model begins a fresh project.
