The use of multi-user architectures for collaborative design has been explored on several types of engineering software. The client-server architecture of STAR-CCM+ allows collaborative simulation set-up for Computational Fluid Dynamics models. Simulation operations are completed by the server and commands are sent to the server by the client. By using the client-server architecture, users can partition the workload of the simulation set-up and decrease the time required to prepare a simulation prior to solving.
Five models are tested to measure the time savings that can be achieved through a collaborative set-up and to explore the functionality of STAR-CCM+ capabilities used in collaboration. These include geometry surface preparation, meshing, and defining physics conditions, as well as fluid flow and conjugate heat transfer solutions. Results from multiple tests on each of these models show that not all operations are compatible with others that may be executed at the same time, but that planning and communication between users allows for a complete set-up and analysis of each simulation.
Results show a time reduction of up to 35% in user set-up time with two users working in collaboration.
