Including additional input files for thermal analysis

Include File specifies additional input files to include in the thermal analysis. These input files are read by the solver in conjunction with the main thermal solver input file, INPF. You can select either a single include file, or a file that names up to 500 other files to include. Included files can be user subroutines or files in the INPF file format.

To create a file that names other files to include, create a text file with each line containing the path and file name of the file to include using the following format.

include file list name_of_include_file_1 name_of_include_file_2 ... name_of_include_file_N

That is, the first line must be "include file list" followed by the list of include files.

The Include File feature allows advanced users to controllably adjust the thermal solver by including custom files which communicate with the solver.
