The Natural Helmholtz-Hodge Decomposition for Open-Boundary Flow Analysis
Found in: IEEE Transactions on Visualization and Computer Graphics
By Harsh Bhatia,Valerio Pascucci,Peer-Timo Bremer
Issue Date:November 2014
pp. 1566-1578
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
Found in: 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
pp. 75-82
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...
