SCIRun is a modular dataflow programming Problem Solving Environment (PSE). SCIRun has a set of Modules that perform specific functions on a data stream. Each module reads data from its input ports, calculates the data, and sends new data from output ports.
In SCIRun, a module is represented by a rectangular box on the Network Editor canvas. Data owing between modules is represented by pipes connecting the modules.

SCIRun is a Problem Solving Environment (PSE), for modeling, simulation and visualization of scientific problems. SCIRun now includes the biomedical components formally released as BioPSE, as well as BioMesh3D. Model scientific problems with this tool.
