Thresholding
The parameters in the Thresholding panel of the Stochastic Field Thresholding dialog define the criteria for the segmentation threshold applied to the generated stochastic field to obtain the structure. The available parameters are Solid Volume Percentage / (%), Grammage / (g/m2), Density / (g/cm3) and Weight Percentage / (%).
When Grammage, Density, or Weight Percentage are chosen as stopping criterion, the temperature must be set as additional parameter in the Material panel. The density of the constituent materials will be set with respect to the chosen temperature based on the Material Database.
When choosing Solid Volume Percentage, the Temperature parameter is not available.
Solid Volume Percentage
Solid Volume Percentage (SVP) determines the fraction of the total volume in percent that the structure should have. Accepted values range from 0% to 100%.
For example, a structure with a Solid Volume Percentage of 40 consists of 40% solid and 60% void space. Porosity is defined as (1 – SVP/100). The threshold to segment the stochastic field is chosen to match the given SVP. Observe the difference in a structure when varying the solid volume percentage from 5%, to 20%, and finally to 40%, while all other parameters are left unchanged.

Grammage
The Grammage / (g/m2) determines the mass per unit area (in the XY-Plane) of the resulting structure. When Grammage is chosen as stopping criterion, the Density / (g/cm3) of the Bulk Material must be defined in the Material panel and the temperature must be set.
|
Density
The Density / (g/cm3) of the resulting structure depends on the density of the chosen materials. It cannot be set smaller than the lowest occurring density or larger than the highest occurring density.
|
Weight Percentage
The Weight Percentage determines the weight of the created object in relation to the weight of the whole structure (including the pore material). Choosing this option only makes sense when the density of the Pore / Matrix Material is greater than zero. Otherwise, the domain will stay empty. See Material and Preview for more information.
