Does OpenFOAM have a GUI?

HELYX-OS is an open-source graphical user interface (GUI) designed by ENGYS to work natively with the standard OpenFOAM libraries provided by the OpenFOAM Foundation and ESI-OpenCFD. The GUI is intended for academic use and entry-level CFD work, and it is delivered to the public under the GNU General Public License.

How much space does OpenFOAM take?

The rule of thumb I usually use with OpenFOAM is that 1 million cells require 1GB of RAM for the mesh alone. As for hard-drives, if the budget is limited, stick with the normal 1TB hard-drives and stay away from SSD flash disks. As for graphics card, it also depends on the sizes of the meshes you’re going to use.
