The application discloses a model-based deep space exploration communication constellation system design method, and belongs to the field of spacecraft digitization technology.The method comprises the following steps: constructing a unified digital model as a single data source throughout the whole life cycle; capturing stakeholders and their interaction interfaces through business scenario analysis, and obtaining top-level service indicators by decomposition to construct a problem domain model; taking the problem domain model as input driving, performing white-box analysis on system capability and architecture, generating a preliminary design scheme containing key parameters, and associating the key parameters to the top-level service indicators; taking the preliminary design scheme as input, performing refined design on system behavior and physical architecture; integrating professional simulation tools to perform computable verification on the key parameters, and automatically updating the corresponding parameters in the preliminary design scheme; and automatically generating a satellite development task book based on the iteratively converged design scheme.The application realizes full-chain digital forward design of a deep space exploration constellation system from demand to satellite.

This invention discloses a parallel contact detection method for FDEM based on dual-domain activation, comprising: constructing a hash domain and a contact domain; dividing the problem domain into hash units; marking hash units containing TET4 units as active states; and constructing a contact domain centered on the host unit according to spatial neighborhood rules; sorting the TET4 units according to hash keys; traversing the sorted sequence to count the number of units in each hash unit, generating an index interval, marking the active states, and constructing an active unit list; based on the active unit list, sequentially selecting the host hash units, determining the visitor hash unit set according to spatial neighborhood rules, and performing pair detection on the TET4 units in the host and visitor units after activation state filtering; and generating a global contact pair set through two rounds of scanning for subsequent contact mechanics calculations. This invention, through a dual-domain activation mechanism and parallel sorting using GPU, limits the contact search to local active regions, avoiding global traversal and dynamic hash reconstruction.
