SimTech-quadratisch
SimTech

Stuttgart Research Centre for Simulation Technology and Cluster of Excellence "Simulation Technology": The SimTech project is developing scientific methods and applications in the different fields of modeling and simulation science. Within SimTech, the Institute of Architecture of Application Systems is concerned with the development of a workflow management system that is tailored to the requirements and needs of scientists. This system forms a platform for workflow-based automation of simulations considering increased flexibility and ease of use. Using this platform, simulation workflows can efficiently be modeled, executed, adapted, monitored and analyzed. One fundamental goal in the development of this system lies in hiding the technical complexity underlying the different phases of workflow-based automation of a simulation. Read more...
