Plans and billing

AeroCloud is a web-based tool that allows you to run computational fluid dynamics (CFD) simulations to optimize the aerodynamic performance of your models without setting up any infrastructure.

To run a simulation you need: An active AeroCloud subscription. A certain amount of “Simulation Credits” (from now on just “Credits”), depending on the quality of the simulation you want to run.

Credits

A credit is a virtual currency that is used to purchase simulations. Each AeroCloud user has a wallet that contains credits. If you are a new user you’ll find it initially empty.

The number of credits available on your account is visible at the bottom of the left sidebar or on the billing page.

Two different factors determine the number of credits needed to run a simulation: Simulation quality Number of yaw angles AeroCloud offers three quality levels: Basic simulation - 1 credit Standard simulation - 5 credits Pro simulation - 10 credits

Each yaw angle is a different CFD simulation for our computing infrastructure. For this reason, the number of credits required to run a simulation follows the formula: credits_for_quality * number_of_yaw_angles

For example, a Standard simulation (5 credits) with 3 yaw angles requires 15 credits.

Subscriptions

A subscription is required to use AeroCloud. With a subscription, you pay a monthly fee (or prepay for a year in advance) to get access to the tool and to receive a certain amount of credits each month. New credits will be added to the user account automatically at the beginning of each subscription month and will never expire unless you end your subscription.

For example, if you subscribe on the 3rd of April to a 10 credits plan and use 6 credits during the month, on the 1st of May 10 new credits will be added to your account and your final balance will be 14 credits.

There are three AeroCloud subscriptions available: Basic Recurrent User Running Business Depending on your subscription you will have access to different features. For a list of the features available on each plan please check our website.

Extra credits

If the amount of credits received from your subscription plan is not enough for your needs, extra credits can be purchased on the billing page. Price for extra credits is visible on the website.

Plan upgrades and downgrades

Currently, it’s not possible to upgrade or downgrade a subscription plan. The current subscription must be terminated first, then a new subscription can be started on a different plan.

Cancellation

When you decide to cancel your subscription, and you can do that anytime, you will retain access to the tool until the end of your billing cycle.

Let’s see some examples.

Monthly subscription

If you activated a subscription on the 3rd of April and terminated the same subscription on the 10th of April, the renewal, which was supposed to happen on the 3rd of May, will be immediately canceled. You will be able to access the tool until the 3rd of May. Credits will be available until the 3rd of May, then they will be removed from your wallet.

Yearly subscription

If you activated a subscription on the 3rd of April 2023 and terminated the same subscription on the 10th of October 2023, the renewal, which was supposed to happen on the 3rd of April 2024, is immediately canceled. You will be able to access the tool until the 3rd of April 2024 and you will receive the number of credits provided by your plan monthly until that date.

Free trial

By joining the free trial you can try AeroCloud for free for a month, with two credits included. You can use those credits to run two Basic simulations on your 3d models.

To join the free trial, you have to follow the steps right after signing up to AeroCloud. We ask you to enter your billing details (this is necessary to avoid any abuse from users joining the free trial multiple times, simulations have a cost). You are free to cancel anytime. If you don’t cancel your subscription before the end of the month, you will automatically join the Basic plan.
