Sjubb runs on 64 bit versions of Windows 7 and Windows 10. You need about 6 GB RAM to run on meshes up to 200,000 elements, and about 16 GB RAM for meshes up to 1M elements.


Fully function trial for 31 days. After this period, the use of Sjubb is restricted to meshes with max 2000 elements. You can buy a license to remove this restriction. In your installed Sjubb version, go to Help→Register to generate a small text file that contains the hardware ID of your computer and your name. You can mail this file to After your payment is received we send you a key that you can insert under Help→Register. The licenses are node locked but allow you to make a few changes to your hardware. If you want to transfer your license to another computer, you need to have or buy a maintenance subscription.


The price of a perpetual license to run the downloaded/installed version is 750 €. This includes updates to newer versions that are released within one year after your purchase. After this, you can buy a maintenance subscription for 250 € per year, which will buy you perpetual licenses of all versions that are released during that year. The license renewals need not be necessarily issued for the same computer as your original license.
