Summer 2011 Week 3: Multiphysics Simulations: Challenges and Opportunities

July 30, 2011 to August 6, 2011

The Canyons Resort, 4000 Canyons Resort Drive, Park City, Utah


Organizing Committee

  • Lois Curfman McInnes (Argonne National Laboratory)
  • Carol Woodward (Lawrence Livermore National Laboratory)

Scientific Overview

Increasingly, computational science communities are confronting questions about complex physical and engineered systems characterized by multiple, interacting physical processes that have traditionally been considered separately. Solutions that can accurately capture nonlinear coupling among dynamically relevant phenomena while stepping over fast waves or rapid adjustments must be in place before we can realize the potential of next-generation computational capabilities for high-impact policy and decision-making. In particular, consistent implicit discretizations, both spatial and temporal, are paramount to accurate solutions.

Approaches that preserve stability while accommodating multiple physics at differing time scales are essential. Constraints must be included in a manner consistent with discretization and physics. Implicit nonlinear solvers must be made robust to changing dominance of physical processes as time evolves within a model. In addition, automatic strategies for scaling both variables and equations must be incorporated into linear and nonlinear solvers in order to accommodate variables of differing scales that change over the simulation time. Moreover, the rapid increase in the levels of parallelism and heterogeneity of emerging computer architectures bring to the forefront issues of programming models and the practical realities of working with complex codes developed by interdisciplinary teams.

To address these issues, we will host an ICiS workshop on multiphysics simulations. The workshop participants, from both the applied mathematics and computational science communities, will join forces to explore both the challenges and the opportunities in large-scale, PDE-based multiphysics simulations. Targeted areas include the following:

·      Consistent temporal and spatial discretizations for coupling physics, including adaptivity and subcycling
·      Stability analysis
·      A posteriori error estimation for multiphysics applications
·      Coupling approaches that maintain accuracy and efficiency
·      Scalable nonlinear solver algorithms
·      Software design issues for supporting multiphysics
·      Identification of common scientific coupling problems and code design patterns across multiple application domains.

Schedule

Please try to arrive on Saturday, July 30. The workshop program starts on Sunday morning, July 31, with a kick-off event. Please check back for an agenda. The workshop closes on Saturday, Aug  6, by noon.

Lodging

The Canyons resort is a fully staffed, full service resort. The ICiS Summer Institute block rate of $96 per night (plus tax and fees) for guest rooms (single occupancy) is guaranteed from Saturday, July 30 to Aug 6. The group rate for a one-bedroom is $139 and a two-bedroom at $159. If you wish to extend your stay beyond August 6 and are not a registered participant of the August 6-13 ICiS workshop, your nightly rate is subject to change.

Reservations may be made via the Resort Reservations Department at 888-CANYONS (226-9667). You must reference the group name (ICiS) to get the group rate. You will need to provide your credit card information to guarantee your reservation. May 1, 2011 is the deadline for lodging reservations.

You can reduce costs by sharing a room with another workshop participant. If you are interested in this option, contact us at <support@icis.anl.gov> and we will assist in pairing up individuals depending on space availability. You may choose to make your room sharing arrangements independent of us as well.

The Canyons (Silverado Lodge) provides complimentary high-speed wireless Internet in all guest rooms, public areas, and function spaces. Other amenities include: use of lodge fitness center, heated outdoor pool and hot tub, and underground heated parking. There are several restaurants located within walking distance. There is also a complimentary shuttle service within the resort. Contact the front desk agent to make arrangements for this service.  

Daycare at The Canyons

Little Adventures Daycare is a state licensed day care facility and cares for 6 weeks to 6 years of age. Private babysitting services are also available. http://thecanyons.com/kids_corner.html

Shuttle Service (All Resort Express Airport Shuttle)

A 40-minute direct shuttle between the airport and The Canyons is $37 +tip for a one-way shared ride (specify shared ride when making reservation), and leaves every 20 minutes regardless of number of shares. This amount doubles for shuttle service between 11PM and 7AM. For a private ride the cost is $150 + tip and up, one-way. All shuttle service arrangements must be pre-arranged via the toll-free reservations line at 1-877-658-3999 no later than 48 hours prior to your arrival. You will be asked to provide your flight information. 48 hours notice is required for all cancellations.

The check-in counter is located at the ground transportation counter adjacent to the baggage claim area at Salt Lake International Airport.

Rental Car

The following car rental companies have counters in Salt Lake City International Airport: Advantage, Alamo, Avis, Budget, Dollar, Enterprise, National, and Thrifty. Make your reservations via the company website or via a travel engine like Expedia.com, Travelocity.com, or Orbitz.com.

·      Parking is free at The Canyons Silverado Lodge.
·      Park City has a free local transit system.
