The Natural Helmholtz-Hodge Decomposition for Open-Boundary Flow Analysis
IEEE Transactions on Visualization and Computer Graphics
By Harsh Bhatia,Valerio Pascucci,Peer-Timo Bremer
Issue Date:November 2014
The Helmholtz-Hodge decomposition (HHD), which describes a flow as the sum of an incompressible, an irrotational, and a harmonic flow, is a fundamental tool for simulation and analysis. Unfortunately, for bounded domains, the HHD is not uniquely defined, t...
Edge maps: Representing flow with bounded error
2011 IEEE Pacific Visualization Symposium (PacificVis)
By Harsh Bhatia,Shreeraj Jadhav,Peer-Timo Bremer, Guoning Chen,Joshua A Levine,Luis Gustavo Nonato,Valerio Pascucci
Issue Date:March 2011
Robust analysis of vector fields has been established as an important tool for deriving insights from the complex systems these fields model. Many analysis techniques rely on computing streamlines, a task often hampered by numerical instabilities. Approach...
