Module groups

source code

The definition of all the MBDyn groups. The top class of that module is ItemGroup, an abstract class that will be the base of a list of nodes, NodeGroup, or a list of elements, ElementGroup. The motivation is to access any object inside a group by a list syntax once the parsing of the MBDyn input file done. As the simplest example:

   >>> wm = WraptMBDyn("input_file")
   >>> wm.init()
   >>> node = wm.nodes.structurals[0]

node is a reference to the first structural node written in the input file. Another example:

   >>> for node in wm.nodes.structurals:
           print node.label

       1001
       1002
       1003
   >>> node = wm.nodes.structurals.get_from_label(1002)

The groups can be iterated as list. Moreover by knowing the MBDyn label used in the input file, any reference to the C++ instance can be got as a Python object.

The work of the group is also to answer to the convert method called by Groups, and thus get down from the MBDyn polymorphism.

Note also GROUP_TABLE, a dictionary gathering the group descriptions for nodes and elements in a table (or list of tuples). Inside a table, the first field is the MBDyn name of the group (used as an enumeration in the C++ code). The second is the attribute name that will be set in the Groups class. The third and last field is the class reference of the group, so then WraptMBDyn will be able to create the group class during its init method.
