| Operating system (server) | Windows server 2022 64-bit | Windows server 2025 64-bit |
| RAM | 8 GB | 16 GB or more |
| Graphics card (for use of 2D GPU solver only) | - CUDA enabled NVIDIA GPU card with computing capability (cc) of 5.2 or higher - NVIDIA drivers at version 461.33 or later Check your GPU computing capability on the [NVIDIA website](https://developer.nvidia.com/cuda-gpus) |
| Monitor resolution | 1024 x 768 | 1920 x 1080 with display setting at 100% or greater |
| Hard-disk space | 1.5GB for installation + space for model files (please note these can get very large) |
| Internet | Internet connection is required at all times if using a cloud-based licence |

### OS

There are no versions available for Unix-like systems. A workaround is to run Flood Modeller from a Virtual Machine that has Windows installed. Alternatively, Windows emulators can be utilised to run Flood Modeller on a Mac or certain Linux distributions, for example.
