Many multi-physics codes designed to solve large-scale applications implement approximate models to capture microphysics.  But with advances in detector technology, experimental data is now producing much more detailed information that has begun to demonstrate the limitations of such methods.  At the same time, computational modeling is now allowing us to study this microphysics in much better detail.  Scientists in a wide range of fields have been studying methods to better capture the details of the microphysics into macroscopic codes to more-accurately solve large-scale applications.  In this workshop, we bring together scientists in the fields of plasma physics, hydrodynamics and turbulence, reactive flows, materials physics, biophysics and earth systems to discuss current methods in scale-bridging and reduced order models.  New data mining and machine learning methodologies have also been developed to improve such model developments.  Although there has been considerable progress in scale-bridging methods recently (or perhaps because of this rapid progress), communication pipelines between different fields (applications, physics and mathematics) are not well developed.  This workshop is designed to develop these communication pipelines.

Topics include:

• Turbulence

• Reactive Flows/Energetic Materials

• Plasma Physics

• Earth Systems

• Biophysics

• Materials

• Radiation Hydrodynamics

Format:

Although we will have a focused meeting (4/22-4/26) with many speakers, the intent of this meeting is to mimic the style of KITP/Aspen style workshops with few talks and lots of discussions. From 4/29-5/23, we will work together to discuss and work on our understanding of scale bridging.

Goals:  

• Share current state-of-the-art in a broad range of disciplines.

• Identify techniques that can cross disciplines to accelerate methods development in different fields.

• Integrate advances in data mining and machine learning to scale bridging efforts

• Identify methods to verify and validate these new models

Deliverables:

• Review paper on this topic

• New application or new approach developed (stretch goal)
