There are hard-coded memory limitations associated with web applications running in a browser. A memory limit of 4GB ram is imposed on any tab, regardless of the amount of hardware installed on a users machine. As such there are a few limitations to be aware of in the online version of Cyclone. These include:

  • Generally speaking large models may impinge on the memory limitation, this this really depends on the geometry. A large model of boxes will take up far less memory than a large model of complex geometry.
  • Arrays can cause memory issues, by default arrays are turned off, but can be turned on again. It is down to the user to make this decision. Again geometry will play a big part in this decision and an array or complex geometry, or nested arrays will likely cause memory issues.
  • Others issues to note, loading large fmesh tallies, CAD or particle track files will additionally take a lot of memory that might not be available to them or impact the rendered performance.

These limitations are associated with using the browser. We have a standalone version of the software nearing completion, which will eliminate some of these limitations. Large geometries will always be hard to view, but the 3D raytracer that is incurrent development will require much less memory that the current viewer and as such will be able to render arrays and large geometry in a much more stable manner, ultimately restricted then to the hardware that is installed on a users machine. The standalone version of Cyclone will also allow Enterprise customers to install it on secure systems that cannot be connected to the internet.
