Abstract
The flexible finite element analysis (FEA) modeling process is addressed within the framework of scripting programming language such as ANSYS Parametric Design Language(APDL). Resorting to recently proposed upper ontology and specific ontology, the FEA modeling processes are expressed as the entities and relations among entities in an ontology tree. An algorithm to obtain a script fragment grammar (SFG) that describe the combination rules of script fragments by instantiating FEA ontology tree is provided. In addition, a method of automatically generating FEA parametric scripts based on SFG derivations is proposed. Then, the whole procedure is applied to develop an automatically generating FEA script software for an air separator product family. The proposed method can effectively reduce repetitive operations in the parametric FEA modeling process, which thereby improves the overall efficiency of the FEA modeling process.
