Stochastic Roughness
Stochastic Roughness roughens the surface of the material ID selected with Rouhgen Material ID. This is done by adding and/or subtracting voxels in the surface following a stochastic distribution.
The parameters in the Stochastic Roughness panel specify the roughening process. A stochastic field is created and segmented depending on the given parameters. It works similar to the Stochastic Field Thresholding.
Background ID
Only the area where the selected material ID (Rouhgen Material ID) and the Background ID touch is defined as surface and thus, roughened.

Feature Radius
Change the Feature Radius to change the size of the added and subtracted features. The Feature Radius is the 99.7 percentile radius of the features, similar to a maximum grain radius.
|
Max Distance
The Max. Distance specifies the displacement of the features from the surface, influencing the layer height. If the Maximum Distance is chosen higher than the selected Feature Radius, not all features are connected to the surface, unless Check Connectivity is selected.
This can be observed in the following figure on the last structure with a max distance of 10 µm and a feature radius of 3 µm.

Operation
Select which Operations should be allowed for roughening. By default, Adding and Subtracting features is allowed. But it is also possible to choose Only Add or Only Subtract from the pull-down menu.
|
Keep SVP
If Add and Subtract is selected, the checkbox Keep SVP is available. Check to keep the original solid volume percentage of the structure by using the same number of voxels for adding and subtracting.
|
Check Connectivity
If Check Connectivity is selected, all features will be connected to the original structure even if the chosen maximal distance is very high.
