Learn how to warp a Cell Map using a field.
- Warp Cell Map (Beta) To turn on Beta blocks, go to File > Settings and check the 'Show Beta Blocks' box.
- nTop 3.14.3
1. Preparing the field to warp the cell map:
Point Maps can be used as fields with the Field from Point Map block.
- Point Map: Topology Optimization Density Point Map
- Result: Topology Optimization
- Interpolation and Extrapolation (Interpolation and Extrapolation options for creating a Field from a Point Map)
Another method is to obtain the field by dragging and dropping the chip from the properties menu.
2. Set up the Ramp: Add a Ramp block (How do I use the Ramp block?)
- Scalar field: Set Field Bounding Box
- Scalar field: Density Field
- Bounding box: Bounding Box of the Body created from Topology Optimization Result
- In min: 0
- In max: 1
- These values are set based on the field that is used as input and can be obtained on HUD.
- Out min: 0.5
- Out max: 2
- The values here are the scaling factors for the cell size.
- Contunuity: Geometric (C0)
3. Create your base Cell Map: This is the cell map that we are warping.
- Add a Rectangular Cell Map block (in this example, we use the Rectangular Cell Map block, but you can use whichever cell map you prefer)
- Volume: In this example, we are trying to create a lattice structure using the topology optimized body. Add a Smoothen Body and Implicit Body from Topology Optimization.
- Cell size: 5,5,5
Tip: To learn more about converting the result into implicit body follow the instructions here (How to run a topology optimization)
4. Warp Cell Map:
- Cell Map: Base Cell Map
- Discretization: 100,100,100
- We choose a bigger number here for the grid size to increase the details that could be captured from sizing fields.
- U, V, W scale: Ramp
