The invention provides a multi-
solver CFD self-
correction method and
system based on semantic
orchestration, and the method comprises the steps: carrying out the retrieval and slot filling
processing of multi-
modal input, and generating a
simulation intention intermediate representation; carrying out structured
verification, default completion and mechanism examination to obtain
reachability classification; mapping is established for a CFD
solver, and short-distance concurrent trial running and preferential long-
distance running are carried out on an equivalent example and
job description compiled into a target
solver through a mixed strategy; the method comprises the following steps: collecting a structured
fingerprint in a running period, generating a minimum change set only reaching a necessary field when a triggering condition is established, writing back to an intention layer, and automatically recompiling and continuing running after the intention layer is formed; and introducing a
physical information neural network and a digital twinborn body to provide suggestions or approximate fields, generating reports, and performing Hash signature archiving on
measurement point and section data. According to the method, the
correctness and the
traceability are ensured, and meanwhile, the one-time runnability, the cross-solver transportability and the
engineering efficiency are remarkably improved.
