Geometry Preprocessing

Processor Operations

• GeometrySource: Loads a geometry in a .stl file format.
• GeometryTransformation: Applies a transformationmatrix on the loaded geometry, when enabled.
• GeometryClose: Closes holes in the geometry up to a certain thickness, when enabled.
• GeometrySmoothNormals: Smooths the geometry artefacts, when enabled.
• GeometryInsideTest: Switches the geometry to a volume such that the VesselGraphCreator can be applied.
• VesselGraphCreator: Creates a vessel graph as described in Vessel Graph Extraction
• FlowIndicatorDetection: Allows to configure the conditions needed for the simulation. For example, the vessel graph of the geometry gets analysed, such that Inlets & Outlets can be defined.
• FlowParametrizationEnsemble & FlowParametrizationRun: Various amount of parameter settings for the simulations.
• FlowSimulationCluster & FlowSimulation: Two processors to create the simulation depending on the OS and capacity OpenLB integration in Voreen
