Payments & Billing

  • Free Subscription — is ideal for a single engineer or collaborators working on small projects. Free Subscription gives users 10 Core-Hours/ month and ability to purchase additional core hours for $10/ Core-Hours On-Demand.

    Team Monthly Subscription — $1,000 USD/ month. Is suitable for small engineering teams. This package provides 150 Core-Hours/month and ability to purchase additional core hours for $8/ Core-Hours On-Demand.

    Team Annual Subscription — $12,000 USD/ year. Is suitable for small-medium sized engineering teams. This package provides 2000 Core-Hours/ year and the ability to purchase additional core hours for $8/ Core-Hours On-Demand.

    OnScale for Enterprise Customers

    Our Enterprise package is a custom package for large engineering teams. It starts at 6000 Core-Hours/ year and goes up from there. The bigger the Core-Hour commitment, the lower the cost per Core-Hour. For more information and to request quote, please contact sales@onscale.com.

    OnScale for Academic Customers

    OnScale is proud to support engineering research and education! We offer Free Student Licenses for university students and greatly reduced Academic licenses to university researches and instructors.

    We recommend starting with our Free Subscription with 10 Core-Hours / month and no limitations on the software, users or features.

    For additional simulation capacity, we offer Academic pricing for Team Annual Subscription. For more information on academic pricing, please contact sales@onscale.com.

  • For Team Subscriptions, OnScale accepts the following payment methods: Credit Cards (Visa, MasterCard, American Express, Discover, JCB, Diners Club), Purchase orders.

    For Enterprise Subscriptions, OnScale accepts Credit Cards and Purchase orders. All Enterprise Subscriptions are paid annually in advance.

  • If you received an error while we attempted to charge your credit card, please double-check your payment information and try again.


    You will need to contact your bank for the reason why the card was declined. Here are a few of the most common reasons why cards get declined:

    - Incorrect credit card details (name on the card, credit card number, expiration date, CVV)

    - Insufficient funds;

    - Some banks will reject charges based on location;

    - Some banks will reject charges based on their own fraud rules;

What is The Cloud

  • The cloud is a server computer located in Amazon AWS server farm at a remote location in which OnScale solver is installed.

  • (Where does my job go?) Your simulation input file is encrypted to ensure a high data protection and sent to Amazon AWS sever where the solver process and calculate your results. Those results are then saved in the cloud and need to be downloaded back to your local computer.

  • As your simulation is done on the Amazon AWS cloud server, the results are saved there by OnScale solve in a special encrypted location. You can access to this location with your OnScale account and download them on your computer by clicking through the "storage" window in OnScale.

  • When you launch an analysis with OnScale Cloud Solver, you spend from your reserve of Core Hours. The estimator is a small program which calculate how much time the first step of your analysis takes and provide with an estimation of the final analysis time and the Core Hours required to run the simulation.

  • When you do simulation, you are hundreds of parameters that you can set and which have all an influence on the simulation results. The traditional way is to change a bit each of them and to see how the solution vary. If you do that one simulation after one another, you will have to run hundreds or thousands of simulations one after the other, monitor the parameter changes and the results, make some screen captures and curves, this can quickly transform itself into a huge task.

    OnScale allows to set up some parameters that can vary in between certain numerical bounds and "sweep" through those parameters to quickly launch on the cloud hundreds of simulations in parallel with just one parameter changed. Results can then be handled by batch using script and what is called the "design space of the solution" can be reconstructed!

    This method is much faster and efficient than the old sequential trial and error method and allows you to make real breakthrough in the design of high end systems designed, because you can quickly find through an optimization study the right combination of parameters.

  • In Cloud computing, a "job" is not what you would usually think it is…

    A job is a computing task that the server must execute and process.

    Typically, all the information required for a job are written within a text file (number of cores, memory, program to be use, links to input files, etc.… ) and this text file is sent to the remote cloud server where a "job" is created.

Cloud Scheduler

  • Check your input deck has the symbx definition for the quantity you would like to sweep in a design study. The Cloud Scheduler will detect any variable definition using symbx.

  • Create Comma Delimited file with your editor of choice (Office Excel, Notepad++ etc.). First row should contain the parametric variable names separated with commas. Each subsequent row is a new simulation with the defined variable values. Parametric variables must be declared using symbx in the flex input file.

  • Use the Abort button to kill all simulations which will allow you to start a New Simulation in the Cloud Storage window.

Cloud Storage

  • Hold SHIFT or CTRL + LMB to select any result(s) you would like to download. Use the Download button or RMB Context menu to download the results to a local directory.

  • Select any result(s) in the Cloud Storage window and use the RMB context menu to Delete. Dependant on folder size, this may take a couple of minutes.

  • Use the Abort button to kill all simulations which will allow you to start a New Simulation in the Cloud Storage window.
