If you only see a black screen after starting a simulation then it could be because of your computer not meeting our minimum requirements, or that there's an issue with your browser. Therefore please try the following:

  • Ensure that your computer graphic card meets the minimum requirements listed here, and that your computer in general meets them.
  • Switch to another browser and preferably either Chrome or Firefox. This means if the issue occurs in Chrome, then please start the simulation in Firefox. And if the issue occurs in Firefox, then please try using Chrome.
    Also, please make sure your browser is updated with the latest version.
