Open course on SCHISM modeling system
Seamless modeling from creek to ocean on unstructured grids
...sponsored by
Reves Faculty Fellowship, College of William & Mary
- Instructor: Joseph Zhang
- Registration fees: none
- Language: English
- Time: April 18 to 20, 2018
- Venue: Ammerlander Heerstraβe 231, 26129 Oldenburg (Univ. of Oldenburg), Germany.
Here is a
map.
- How to get there:
- Nearest airport: Bremen, Germany.
- There is a shuttle service from the Bremen airport to Oldenburg
(e.g. to the hotel or to the Ammerlander Heerstraβe 231), which
requires the following info: Day of flight, fligh number, a cell phone contact.
This is perhaps the easiest option.
- The 'Straβenbahn' in Bremen takes around 15mins from the Airport to the central
station, where there are several trains going to Oldenburg. Take the STR6 heading
to "Universitat" and exit at Hauptbahnhof. The STR6 go every 10mins.
- The DB trains - Inter City (IC) and Regional Express (RE) - take 30mins to
Oldenburg central and the NWB trains take 38mins, the latter also going to Oldenburg Wechloy (near the workshop site),
so effectively, there are two trains per hour going to Oldenburg. They usually go from
plattforms 3 at Bremen central. The IC and RE usually go to Emden or Norddeich as a
final destination, and the NWB goes to Bad Zwischenahn.
- The probably cheapest option is to take a "Niedersachsen-Ticket", which costs 23Euros for
one person and an additional 4E each for up to 4 more people, so 23E for one, 27E for two,
... and 39E for 5 people. This ticket is also valid for Busses and the Straβenbahn
(and between Bremen and Oldenburg, also for the IC), for the whole day,
but only after 9am. You can buy it at ticket machines, in the Straßenbahn,
online at https://www.bahn.com/en/view/index.shtml or via the App "DB Navigator".
You can book it in advance and print it out.
- For public transportation inside Oldenburg, I recommend daily tickets. They cost the following:
- 1 Person: 9,20 EURO
- 2 Persons: 11,80 EURO
- 3 Persons: 14,40 EURO
- 4 Persons: 17,00 EURO
- 5 Persons: 19,60 EURO
- single tickets cost 2,45E per ride, or 8,20E for a "4er Ticket",
which is valid for four individual rides.
- Within Oldenburg, you can take Bus 310 (Pophankenweg, about 100m) or 306 (Grotepohl) to workshop site.

Course syllabus
Unstructured-grid (UG) technology has significantly matured during the last decade.
Traditionally, UG models are applied to nearshore applications (rivers, estuaries,
bays), but recent advance now allows their use in the deeper ocean (the
so-called 'eddying regime'). We have presented some key requirements for this
type of applications in Zhang et al. (2016).
The addition of eddying regime capability in our UG model (SCHISM)
significantly expands its scope, and makes it possible to use a single
UG model from very shallow (inundation regime) to very deep water, provided that
appropriate numerical methods are used. The recent introduction of flexible gridding systems
for the horizontal and vertical grids used in SCHISM (Zhang et al. 2015, 2016)
enables model polymorphism that unifies different types of cells in a single UG grid:
1D, 2DV, 2DH, and full 3D, thus greatly enhancing the numerical flexibility and
efficiency for truly cross-scale applications.
In this 3-day short course, I'll explain the fundamentals of the cross-scale SCHISM model,
including the recent new developments on vegetation and ice dynamics. Hands-on tutorials
will be conducted in some afternoons to familiarize the trainees with the basic tools useful
for the modeling system. For trainees with prior UG model experience, I will
highlight the key differences between SCHISM and other models for you to 'unlearn'.
Upon completion the trainees will have acquired basic knowledge on workflow in typical
SCHISM simulations.
We will start at 8:30am and finish around 5pm each day. A draft agenda is given below:
- Day 1: Introduction to SCHISM modeling system; physical formulation; numerical formulation
- Day 2
- Morning: simple set-up and grid generation
- Afternoon: 1 hour presentations from German colleagues; tutorial for barotropic model
- Day 3:
- Morning: model set-up for baroclinic model; advanced topics (LSC2 grid; eddying options)
- Afternoon: tutorial for baroclinic model set-up; discussion with German colleagues
