Each submodel test consists of two input files: the global analysis and the submodel analysis. The global analysis input files start with the letters pg, followed by a five-character element descriptor. A global analysis file for a submodel analysis using the GLOBAL ELSET parameter on the *SUBMODEL option ends with g; each such analysis uses the same analysis procedures and produces the same results as the corresponding file without the g appended. If more than one *SUBMODEL option is used in a submodel analysis, the file name of the global analysis file ends with gm. The last character (excluding g and gm) for all global analysis files except those for shell-to-solid submodeling contains information about the procedure type used: m stands for multiple-step analysis, s for static, h for heat transfer, d for dynamic, and q for a sequentially coupled thermal-stress analysis. For shell-to-solid submodeling the last character (excluding g and gm) represents the geometry tested: p stands for patch, f for uniform flat plate geometry, and c for cylindrical geometry.

The submodel analysis input files start with the letters ps, followed by a five-character element descriptor. A submodel analysis file using the GLOBAL ELSET parameter on the *SUBMODEL option ends with g; each such analysis is a duplicate of the corresponding submodel analysis file in a submodel analysis without the g appended. If more than one *SUBMODEL option is used in a submodel analysis, the file name ends with gm. The last character (excluding g and gm) for all submodel files except those for shell-to-solid submodeling describes the mesh variation or the procedure type used. For shell-to-solid submodeling the last character (excluding g and gm) of the submodel input file indicates the global element type that is being submodeled: this character is 1 for global S3/S3R, 2 for global S4R, 3 for global S8R, 4 for global STRI3, and 5 for global S4.
