Programming Rules for Cad*I ProcessorsThe CAD*I environment consists of a set of internal CAD*I processing programs interfacing external products such as CAD systems, FEM computational programs. All interface CAD*I software should be written in a common FORTRAN 77 subset.

Comments on Post-ProcessorsThe post-processor has the task to interpret the neutral file and to build an internal representation of the transferred model in the receiving CAD system. The post-processor consists of the following modules:

Comments on Pre-Processorsgnificantly on the individual CAD system, a basic algorithm for the translation process from CAD system data base to the neutral file can be formulated: The main purpose of this algorithm is to ensure the neutral file is sequential.

结果

The Interface of the CAD*I Parsernother CAD system can now be restricted to the analysis of semantics and building up the data structure. This chapter describes the theoretical basis for the parser and its interface to later phases of post-processing.

a base, finite element analysis, experimental analysis, and advanced modeling. The definitions of these interfaces are being elaborated in harmony with international standardization efforts in this field. One principal goal of the project is to develop techniques for the exchange of CAD information

The High Level Data Specification Language HDSLs). Besides, certain T-specific properties (T-Axioms) Are valid for these constansts (semantic of T). For example, the type NATURAL defines the set N=(0, 1, 2, 3, 4, 5 ...) of NATURAL constants, where the relation 2=Suc(Suc(0)) is one of the T-Axioms (Suc denotes the successor function /Suc(X):=X+1)
