Multics Documentation
Version: v3.0.0
Last Updated Feb 20, 2025
Multics is a cross-platform, multiphysics modeling software for positive displacement machines, enabling rapid design assessment and optimization. Multics simulates the operation of hydraulic pumps/motors, considering the micromotions of internal parts, their deformation, and power losses in the lubricating films. It also accounts for fluid aeration and cavitation. The software is highly configurable for different types of pumps and motors. The current presets include swashplate axial piston machines, external gear machines, internal gear machines, and gerotors.
