In this webinar, we discuss what’s new in FLOW-3D v11.1 and demonstrate how to use the new models and features. Flow Science’s recent developments for the FLOW-3D v11.1 solver include advances in capabilities, accuracy, and performance. One of the most exciting new features, Active Simulation Control, is the ability to control time-dependent events with probes placed in the computational domain. Water and environmental users will benefit from new hydraulic inlet/outlet boundary conditions that are enhanced with the addition of rating curves and automatic calculation of fluid depth. These additions simplify the setting on inlet boundary conditions when modeling sections of rivers and open channels. A new interface to topographical data has been developed. Raster-format topographical data can be used not only for defining geometry, but also to characterize surface roughness using mapping data. Other additions include a model for simulating mooring lines, improvements to the sediment scour model, a wave absorbing layer for damping wave reflections, and an extended cavitation model. The user interfaces of FLOW-3D and FlowSight™ have also been substantially improved guided by a design philosophy of increased usability. In addition to the new capabilities that accompany the latest physical models, the major enhancements in the upcoming release of the user interfaces are themed around a better control over the workflow and automation, particularly for post-processing and report generation. With batch post-processing, the user can request the post-processed results ahead of time, especially for simulations with repeated workflows and large results files and then, generate html-based reports that can be easily shared to communicate results and analyses.
