Automated gap detection and removal in geometrical or three-dimensional models for enhanced simulation readiness

A system for automatically identifying and sealing gaps in a three-dimensional (3D) computer-aided design (CAD) model for simulation, the system comprising:

• a processor configured to execute instructions stored in a memory to perform gap identification and sealing;
• a multi-volume meshing module configured to generate a mesh encompassing all CAD bodies and surfaces of the 3D model relevant to a simulation;
• a boundary definition module configured to define boundaries or points within the 3D model to distinguish inside and outside regions, wherein gaps exist between these regions;
• a solver module configured to execute a Laplace equation over the multi-volume mesh, wherein the equation satisfies the conditions that its primary variable has a maximum value either at the boundaries or in the source term, has a gradient inversely proportional to the area through which it can pass, and results in two constant values for the inside and outside regions in the absence of gaps;
• an iso-surface computation module configured to determine an iso-surface of the primary variable solution and iteratively adjust its value until gaps in the 3D model are sealed at desired locations;
• a volume separation module configured to segment the 3D model into distinct inside and outside volumes using the computed iso-surface, ensuring the gaps are sealed;
• and
• a graphical user interface (GUI) module configured to allow a user to interactively define boundaries, visualize the iso-surface, inspect the sealing process, and selectively delete inner or outer volumes as needed for simulation preparation.
