PySimple1Gen Command

This command is used to construct output files containing material properties for PySimple1 uniaxial materials. The PySimple1Gen command constructs PySimple1 materials (Boulanger, 2003) for pre-defined zeroLength elements.

PySimple1Gen $file1 $file2 $file3 $file4 $file5 <$file6>

$file1	The name of an input file containing soil and pile properties required to define the PySimple1 materials.
$file2	The name of an input file containing information about nodes that define the mesh in the domain.
$file3	The name of an input file containing information about the zeroLength elements to be assigned PySimple1 materials (hereafter called p-y elements).
$file4	The name of an input file containing information about the beam column elements that are attached to p-y elements.
$file5	The name of the output file to which the PySimple1 materials are written.
$file6	The name of the output file to which the applied patterns are written (optional).

The command has been structured such that $File2, $File3, $File4, $File5 and $File6 can be sourced directly by OpenSees from within a master tcl file. Hence $File2, $File3 and $File4 serve two purposes:

They provide information to PySimple1Gen to create the PySimple1 materials.
They can be sourced directly in a master tcl file to define the nodes, zeroLength elements for p-y materials, and pile elements, respectively.

Furthermore, $File5 and $File 6 serve the following purpose:

They can be sourced by OpenSees from within a master tcl file to define the PySimple1 materials and the applied patterns, respectively.

The intended use of the files is demonstrated in an example problem in the Appendix: PySimple1GenDocumentation.pdf
