Integrating a Perl program as a preprocessor.
Parameterization of input curves presents an application of integrating a Perl program as a preprocessor.
The LS-OPT setup specifying the Perl program as a preprocessor with the command and input file is shown in the Figure below.
The parameters are specified in the input file using the LS-OPT parameter format << >> :
0 0 <<x1>> <<y1>> <<x2>> <<y2>> 0.8 <<y3>>
The output of the Perl program can then be used as an input for the LS-DYNA (or any other User-Defined-Solver) step. Select the Run Jobs in Directory of Stage option, or define a File Transfer to make the Perl output available for the solver.
