OpenSees Interpreter

The main abstractions of OpenSees will be explained using the OpenSees interpreter. The interpreter is an extension of the Tcl scripting language. The OpenSees interpreter adds commands to Tcl for finite element analysis. Each of these commands is associated (bound) with a C++ procedure that is provided. It is this procedure that is called upon by the interpreter to parse the command. In this document we outline only those commands which have been added to Tcl by OpenSees.

For OpenSees we have added commands to Tcl for finite element analysis:

• Modeling – create nodes, elements, loads and constraints
• Analysis – specify the analysis procedure.
• Output specification – specify what it is you want to monitor during the analysis.
