To obtain an impression of results of computational fluid dynamics, simulated velocity fields have to be visualized adequately. In cooperation with delta h Ingenieurgesellschaft mbH the software STRING is developed. It enables an intuitive visualization of steady-state and transient three-dimensional velocity fields with the help of pathlets. It is the result of the PATHS project.
Pathlets are comet-like shapes whose length correlates with the local velocity and whose position is given by a short part of a trajectory. Due to an equidistribution of the pathlets in the domain and their movement with the fluid flow, a natural visualization is achieved.
