sphe_add_field_geometry

The sphe_add_field_geometry tool is an advanced version of the sphe_add_field_point tool, allowing you to modify any field parameter for more complex cases. With sphe_add_field_geometry, you can define complex geometries as contours of specific field values. In the example below, two complex surfaces are assigned different density values, resulting in a clear density variation between the two defined geometries.

Usage

Adds a Field Geometry to the project. A field geometry is essentially a function that is calculated using a particular geometry in space.

Double click a field geometry or edit its value using the spherene inspector :

Workflow

The general steps include:

• Create the geometry meshes to which you will assign field values.

• Click the tool button . In the pop-up window (for Mac users) or the command line (for Windows users), select the field parameter you want to modify and enter a new value. Then, click the geometry to assign it the specified field value. You can also modify the field values later in the Spherene Inspector.

• You can repeat step 2 to add more geometries or modify additional fields.

• Click the compute button , select Solid Surface, and start the computation.

Parameters

• Type: Density, Thickness, Surface Bias
• Value: Variable based on Type
• Position: Place and position geometry in 3D viewport

info

Density [%], Thickness [mm], Surface Bias [±1]

Density

Attribute	Value	Default	Unit
Color	Cyan
Range	1 <	5.6	Volume Fraction

---

Thickness

Attribute	Value	Default	Unit
Color	Magenta
Range	0.1 <	0.4	mm

info

As long as you do not have a thickness field point set, the DRT acts as wall thickness by default. You can set the DRT in the compute dialogue

---

Surface Bias

Attribute	Value	Default
Color	Yellow
Range	-1 to 1	0

info

Shifts the Single Surface, minimal surface, from its ideal position to the negative or positive of its normal.
