Programs for Automatic Finite Element Calculations (PAFEC) is a general-purpose, three-dimensional linear and nonlinear finite element program. PAFEC's features include free-format input utilizing engineering keywords, powerful mesh generating facilities, sophisticated database management procedures, and extensive data-validation checks. Presented here is a description of a sofware interface that permits PAFEC to be used as a preprocessor for COSMIC/NASTRAN. This user-friendly software, called PAFCOS, frees the stress analyst from the laborious and error prone procedure of creating and debugging a finite-element model with PAFEC, thus taking full advantage of the free-format engineering-keyword-oriented data structure of PAFEC, the amount of time spent during model generation can be drastically reduced. The PAFCOS software will automatically convert a PAFEC data structure into a COSMIC/NASTRAN bulk data deck. The capabilities and limitations of the PAFCOS software are fully discussed in the following report.
