Dune Solver Documentation

Welcome to Dune Solver! This comprehensive guide will help you get started and make the most of your Dune Solver experience.

Grid Configuration

- Size and Resolution: Customize the size and resolution of your grid to fit your project's needs.
- Height Multiplier: Adjust the overall height of the grid to control the elevation of your landscape.

Sand and Rock Layers

- Layer Levels: Define the levels and heights of both the sand and rock layers to create realistic terrain.

- Height Multiplier: Set the verical scale of the simulation
 
Solver Settings

- Saltation Amount: Control the amount of sand being blown away and deposited. This parameter influences how much sand is transported by the wind.
- Saltation Length: Determine the length of saltation based on the slope of the dune. Steeper slopes result in less deposition, leading to flatter windward slopes and steeper lee slopes.
- Overall Saltation: Set the overall distance particles are moved by the wind, independent of the slope.

Wind Settings

- Wind Direction: Specify the wind direction in XYZ coordinates. Combine this with splines to guide the wind direction more precisely.
- Wind Splines: Use multiple splines for rich variations in wind patterns. Both wind direction and splines are multiplied for complex effects.
- Wind Noise Amount: Adjust the amount of wind noise to add natural variation to the wind flow.

Collision with Objects

- Collision Collection: Create a collection for objects that will interact with the sand and rock layers. Place collision objects within this collection.
- Simplified Colliders: For complex models, consider using simplified colliders to reduce computation time. Note that collision detection is the most compute-intensive part of the solver.

- Advanced Control: For more control, enter the node tree where you can tweak the noise settings for sand and rock. We have created a node group for each layer, allowing for detailed customization.
