Identify the entries required to be present in a Nastran input file for use with Helius PFA.
The entries discussed in this section should be in place to ensure compatibility with Helius PFA and to take full advantage of its superior convergence characteristics for nonlinear, progressive failure problems. More specifically, this section explains the need for these entries in terms of the unique characteristics of the product. This section does not discuss the formatting requirements of any entry, nor does it discuss any of the specific options or data of any entries. These issues are covered in the Use a Text Editor to Convert Input Files section.
Set the current directory in the command line to the file path where the input file is present. This allows Helius and Nastran to write the files to the correct location.
