FlowVis — a CAD based solution for the graphical post-processing of scalar and vectorial data

FlowVis is a visualization tool for graphical post-processing of data defined in a 2D or 3D raster grid. These data typically represent a field of scalar and/or vectorial variables characterizing some physical phenomenon, as for instance, the wind velocity vectors over topography, or the smoke concentration within an urban area. With a wide field of application ranging from Fluid Dynamics and Heat Transfer to Stress Analysis, both in applied engineering and fundamental research, FlowVis provides a quick and efficient way for the graphical display and analysis of data obtained from a numerical model or experimental setup. The software is written in C language and is a subsidiary application of the CAD Microstation, running in PC machines, under DOS or Windows. The present paper provides some insight into the major features of FlowVis and gives some examples of its application.
