ST. HELENS ROOM
Continental breakfast will be available in the St. Helens room at 7:30
am both days. Coffee break service will be provided at about 1:30 pm
on Saturday. Due to exhorbitant catering costs at the Westin, THERE
WILL BE NO LUNCH SERVED EITHER DAY. We'll
be on our own!

I. Presentation of APS Papers

II.Discussion of other ongoing applications
- Rick N.
2-Fluid in RFPs:
2 -fluid effects generate background flows comparable to the flow in
the modes. The flow is sheared (no net momentum). Appears to be a
quasi-linear effect. Has found a suspicious 1/12 mode. Is it real or
is it memorex?
"We'll figure it out." - Carl S.
- Michael Kissick
Michael presented an interesting plot showing the limitations of NIMROD
woth flow. High flow and high S don't work. Some suggestions were
meade te Michael will make, like running with si_in_v=false, etc. We
all appreciate Michael's patience with us. We are committed to slving
- Eric Held
Presented some plans for including his thesis collisionless closure for
the heat flux into NIMROD.
DIII-D high-beta disruption. The straight-line grid has cured the
problem of the numerical mode with Pr=1000. With Pr=10 the bad mode
returns even at beta_n=5. We may not have
the "cure" yet.
2:30 PM - 5:00 PM
- AZTEC (Steve P.)
Good news: Fully implementd in the code.
Bad news: Can't compete with the present
- Higher order elements (Carl)
- Nimset complete
- Nimplot complete
- Nimrod partially functional. Still needs
- Degenerate point
- Regularity conditions
- Parallel seaming
- Extrapolation routines
- Preconditioner development
- CFL condition
- Use of higher order definitions in diagnostics
- Functional form of rz
- Quad. basis definitions exist for orders
1 and 2
- Polynomial orders > 1 not implemented for
Initial tests show that biquadratic representation is much more
accurate for slab tearing mode. Need degenerate point capability to do
more realistic cases (like a tearing mode
in a cylinder).
- Reset capability (Tom)
Exists in Nimset. Tom has found a clever way to search a grid to
answer the question "What cell is a point (r,z) in?". Will allow
complete re-gridding and/or resetting the
- Kinetic closures/particles (Scott P.)
Scott and his graduate student have made progress in the mechanics of
pushing particles in the Nimrod fields.
- Computations on tblocks (Alfonso)
Can't tell from the results presented.
- Pre-processing and web site issues (Scott
Changes to Fluxgrid and the web page were

III. Other technical Issues
- Xdraw (new versions)
Scott presented Nina's results. She has done
an excellent job.
