Installation

Currently the precompiled executable of numgeo is available for the following operating systems (OS):

  • Windows
    • Windows 10 (Note that there have been some reports of compatibility problems for Windows 10. Please report any issues to the developers.)
    • Windows 11
  • Linux
    • Ubuntu (tested versions 20.04, 22.04, 23.10)

While the Windows version of numgeo can only be used in combination with Intel OneAPI, the Linux versions are available for both Intel OneAPI and gcc. Detailed installation instructions and ready-to-run scripts are provided in the respective sections.

If you are using Windows, you do not necessarily need to install Intel OneAPI. If you do not install Intel OneAPI, the DLL files supplied with numgeo must be present in the calculation folder or added to the system path. However, in order to use user-defined subroutines, you will need a compiler, such as available through Intel OneAPI. By default, the tutorials with user-defined subroutines are shipped together with shell scripts using Intel OneAPI to compile the user routines. You will receive an error if you dont have the required compiler installed.

Intel oneAPI

It should be noted that the installation of Intel oneAPI requires a lot of space. If the entire toolkit is installed, the total size of the installation is approx. 20 GB. It is thus crucial to select only the required parts of the toolkit as described in the later sections. With these settings, the required space reduces to 13 GB (which is still quite high).
