OrcaFlex hardware requirements

We are not in a position to evaluate the enormous range of chip and system specifications that are available, so we cannot make specific recommendations about what hardware is best to run OrcaFlex. Multi-core chips provide the best performance to price ratio at the current time. Other than that we simply recommend that you obtain the latest processor/chipset/memory in whatever family fits your other IT and purchasing requirements.

o
There are many general processor benchmark comparison tables available online. If you wish to make comparisons of performance when running OrcaFlex then we do provide a benchmark program (see the link at the bottom of the page). This can be used by you and your suppliers to compare computer performance to determine the optimum machine to purchase.

OrcaFlex can be installed and run on any computer that has:

  • Windows 8.1, 10 or 11. Both 32 bit and 64 bit versions of Windows are supported.
  • If you are using small fonts (96dpi) the screen resolution must be at least 1280×768. If you are using large fonts (120dpi) the screen resolution must be at least 1680×1050.

However, OrcaFlex is a powerful package and to get the best results we would recommend:

  • A 64 bit edition of Windows.
  • A powerful processor with fast floating point and memory performance. This is the most important factor since OrcaFlex is a computation-intensive program and simulation run times can be long for complex models.
  • At least 4GB of memory. This is less important than processor performance but some aspects of OrcaFlex do perform better when more memory is available, especially on multi-core systems. If you have a multi-core system with a 64 bit version of Windows then you may benefit from fitting even more memory.
  • A multi-core system to take advantage of OrcaFlex’s multi-threading capabilities.
  • As much disk space as you require to store simulation files. Simulation files vary in size, but can be hundreds of megabytes each for complex models.
  • A screen resolution of 1920×1080 or greater.
  • A DirectX 9 compatible graphics card with at least 256MB memory for the most effective use of the shaded graphics facility.
  • Microsoft Excel (Excel 2010, or later) in order to use the OrcaFlex automation facilities. Both 32 bit and 64 bit versions of Excel are supported although we strongly recommend the 64 bit version to avoid the severe constraints on memory usage of the 32 bit version.
