Detailed Description

The NeumannModel applies load boundary conditions on specified node groups with configurable load increment control. Unlike point loads, this model can handle dynamic node group configurations and provides sophisticated load scaling and increment management for nonlinear analysis.

Features:

• Load application on multiple node groups with individual DOF types
• Load increment control with adaptive stepping
• Initial load specification and load reduction capabilities
• External scaling support for displacement control
• Maximum load value constraints
