The .cpr file is an OptiStructASCII format results file.
File Creation
This file is created when CONTPRM,PREPRT,YES is specified in an
input file which contains contact.
File Contents
This file contains a summary of initial conditions of contact interfaces. The
information is printed as a separate table for each contact interface in the model.
Currently, .cpr file output is supported for any model with
contact.
File Format
The following table format is used to print the initial contact summary
information. Figure 1.
