How to warp a cell map using fields

Objective:

Learn how to warp a Cell Map using a field.

Applies to:

Lattices
Warp Cell Map

Procedure:

Preparing the field to warp the cell map:

Point Maps can be used as fields with the Field from Point Map block. A Field from Point Map block. The point map is created from a Topology Optimization Density Point Map block.

A Field from Point Map block. The point map is created from a Topology Optimization Density 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. Another method for obtaining the density field is to extract it from the Topology Optimization properties panel.

Another method for obtaining the density field is to extract it from the Topology Optimization properties panel.

**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)

A Ramp block being used to Ramp the density field values.

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)

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
