NAME

Sim::OPT::Morph.

SYNOPSIS

        use Sim::OPT;
        opt;

DESCRIPTION

Sim::OPT::Morph is morphing program for preparing model instances (in text format) to be given to simulation programs in design-aimed explorations. Sim::OPT::Morph is controlled by the Sim::OPT module, which manages the structure of searches.

More specifically, Sim::OPT::Morph can manipulate the text files constituting the description of models for simulation programs. The general function dedicated to that aim recognizes variables by position on the page (determined by row number and position of the list element in that row - no embedding of markers in files) and modifies them through linear variations - so to perform translations ("linear" option), or rotations ("2drotation" option), or text substitution ("wordchange" option) -, and possibly propagation of constraint with user-defined rules.

Additionally, Sim::OPT::Morph features several specialized functions which are specific to the ESP-r building performance simulation platform; those functions can manage the simulation program directly, through the shell, or by manipulating model configuration files. Some of these functionalities involve operations in which the Radiance lighting performance simulation platform is called through ESP-r.

The morphing instructions must be written in a configuration file whose name will be asked at the launch of Sim::OPT. This distribution includes two examples of such files: an OPT's configuration file for an ESP-r model and an OPT's configuration for an EnergyPlus model for the same building and the same morphing operations. (EnergyPlus is another building simulation platform.)

Configuration files for propagation of constraints may be specified in addition to a configuration file. Propagation of constraints can be used to direct the morphing of models and give to the morphing operations greater flexibility. Propagation of constraints can target the model configuration files and/or, in the case of ESP-r, trigger modification operations performed through the shell and regarding geometry, solar shadings, mass/flow network and controls.
