More & Faster Sims

As announced in the vibe coding with Canopy technical article, from 1st May we are upgrading compute allocations to help users make the most of the Canopy API. Medium subscribers will receive 50,000 compute credits, Heavy will receive 200,000 credits, and Super subscribers will enjoy unlimited usage.

One of the key objectives for 2025 was to increase speed. Dynamic Lap runs are now 49% faster for Speedy Pool users, and simulation time on standard nodes has been reduced by 39%, meaning less waiting during mission‑critical times.

Simulation Retry

The most requested feature is the ability to re‑run failed exploration jobs. Dynamic Lap Retry Options address this by slightly adjusting car mass and re‑running the simulation. Simply enable this option when staging a run.
This is intended for minor reliability issues. For major failures, please continue opening Support tickets so the root cause can be addressed.

Robustness

A concerted effort has gone into reliability, clarity, and workflow usability:

• Replaced generic error codes with clear, human‑readable messages

• Improved Dynamic Multi‑Lap reliability, including tyre and brake wear constraints

• Significantly expanded automated testing coverage

• Reworked the deployment pipeline for faster, more reliable releases

• Fixed numerous edge‑case stability issues across niche model combinations

• Improved gLat and gLong signals on banked tracks

• Fixed defects in battery limits, side‑shaft limits, cross‑linked torsion bars, and thermal and power evolution

• Reduced UI page reloads and improved stability by maturing authentication handling

• Eliminated site slowdowns after large simulation version sweeps through improved memory management

• Improved config editor responsiveness

• Filtered NaNs from worksheet statistics so failed jobs no longer disrupt summary views

UI

Additional usability improvements include:

• Custom tabs and charts can now be created alongside standard simulation output charts, simplifying repeat analysis of common tasks

• The last‑viewed tab is remembered to reduce unnecessary navigation when iterating

• The job count is now shown directly in the submit button to avoid unexpected job sizes

• A Manage Components button has been added to Car, Weather, Track, and other configs, allowing management of saved .json component snippets stored in the cloud

• Browser tabs now use meaningful names rather than all appearing as “Canopy Simulations”

• Explorations now display both the base and perturbed parameter values, removing the need to switch back to the config

• Worksheet usability enhancements, including the ability to create a new configuration directly from a worksheet

Simix

Need more than a standard .tir file?

For teams whose simulation needs go beyond generic tire files, MICHELIN SIMIX delivers a powerful upgrade.

The platform provides access to an extensive catalog of tire and chassis datasets, including Pacejka Magic Formula and other formats, covering a wide range of vehicles. With the recent addition of extensive Michelin Motorsports tire references, it can also deliver custom, high‑performance datasets tailored to specific simulation needs.

When standard models fall short, the MICHELIN SIMIX team creates custom datasets using an augmented modeling approach that blends physical measurements with virtual data from Michelin’s digital toolchain. This method incorporates real‑world corrections: surface, temperature, and ground conditions to produce accurate, high‑fidelity simulation models without the usual shortcuts or manual data crafting.

Most datasets are simulation‑ready out of the box for use in Canopy and real‑time simulators, and the SIMIX team can provide technical support whenever needed.
