Presentations

• Talk: What can the Implicit Moment Method Do? (Mar 4, 2014, KU Leuven)
  Pedagogical overview of the capabilities and limitations of the Implicit Moment Method.
• Introductory lectures at KU Leuven on fluid models of plasma:
  • (Nov 28, 2013)
    • Slides: [Derivation of Vlasov, Two-fluid Maxwell, and resistive MHD models of plasma] (particle viewpoint)
    • Handout: [Waves in MHD] (same as what I handed out last year).
    • [Exercise: derive fluid equations].
  • (Nov 29, 2012)
    • Slides: [Derivation of Vlasov, Two-fluid Maxwell, and two-fluid MHD models of plasma] (distribution function viewpoint)
    • Exercises: [Oefening 3]
  • (Dec 06, 2012)
    • Handout: [Waves in MHD]
    • Slides: [Linearization of MHD and two-fluid plasma]
    • Exercises: [Oefening 4]
  • Other helps:
    • Notes: [Solution of the two-fluid source-term system]
• Talk: Two-fluid 20-moment simulation of fast magnetic reconnection, Feb 25, 2013 [version on Lirias]
  The 20-moment model resolves pressure near the X-point better than the 10-moment model based on comparison with Vlasov simulations.
• Talk: Approaches to multiscale coupling of plasma models, Jan 16, 2013
  Semi-implicit (compared to fully implicit) approaches to implementing an efficiently asymptotic-preserving hierarchy for space weather simulation. Presented at the Second Annual SWIFF Meeting.
• Talk: Outflow positivity limiting for hyperbolic systems.
  Presented at RTWH Aachen, Oct 18, 2012 (reworked version of NUMDIFF-13 presentation).
