Welcome to the Fluid Dynamics Software Infrastructure (FDSI) community discussion forum. To enable participation, click Join Room button at the bottom. The goal of this forum is to facilitate discussion among the fluid dynamics community with regard to what they would like to achieve through an NSF sponsored institute dedicated to fluid dynamics software infrastructure under what was formerly called the S2I2 program but is now the Community Cyberinfrastructure Implementations component of the Cyberinfrasctructure for Sustained Scientific Innovation (CSSI). Specific topics have already had some discussion under the FDSI GitHub issue tracking system but we are hoping this additional forum provides a useful alternative. We are hoping to re-engage discussions started during our Kickoff Workshop to better guide the activities during our second workshop.
