Summary CDBM IMAGE meeting, 07

IMAGE SUMMARY

• IMAGE set up to provide a venue for discussion between the different Integrated Modelling (IM) activities. Scope:– Standardization of formats and interfaces

• Starting point for collaborations week long meeting in Cadarache hosted by ITER in early September

– Machine descriptions– Transport Solvers

• Initial work was originally expected to start this meeting– Delayed as an IMAGE project activities in partners though

– V&V metrics and standardized test cases– Software Standards

• Short IMAGE session only in this meeting:– Report on the ITER IM meeting– Plans and status of the IM projects

ITER IM Workshop (Houlberg)

Status report from the first ITER Integrated Modelling workshop – 1 week meeting three weeks ago– Participants from EU, US, JP, RF and ITER– Focus on data structures and code interfaces

• Detailed topical discussion on code interfaces• Collaborative opportunities – harmonizing data structures

– EU ITM data structure implementation(CPO’s) “template” to base future discussions on

• Framework tools– US KEPLER tool “paradigm” for application framework?

– ITER rather than ITPA host for continued “IMAGE” work?

Future topics to be addressed:– Enhanced coordination of scenario modelling between

ITER and the ITER parties– Verification and validation procedures

Plans and Status of partner programs

• JP (Yagi)– BPSI (TASK, Topics-IB and Sonic)

• Staged development phases with 2 & 5 year horizons

• RF (Konovalov) – Continued efforts centered around ASTRA + DINA

• Aligned with ITER shorter term needs

• EU (Strand)– ITM-TF simulation tools, integration technologies 2 + 5 year

horizon. • US (Bateman)

– Report on the FSP Workshop Report. Start FY 2009: 5 + 15 year horizon scaling up to 28M$/yr

http://www.lehigh.edu/~infusion/FSP_report.pdf– Ptransp status and plans on the 2.5 yr Horizon.

• Collaboration opportunities: facilitate sharing of modules and tools - data structures and tools.– Bilateral exchanges of tools and ideas– Discussions guided / “moderated” by ITER

BPSI-plans and status

TASK code is under development as a core code of BPSI and now TASK V1.02 is available as an open source.

http://bpsi.nucleng.kyoto-u.ac.jp/task/

• developing BPSI data interface (BPSD) including standard data set anddata exchange interface, taking account of the compatibility with EU ITM-CPO and US SWIM-Plasma State.

• BPSI execution interface (BPSX) is also under development for integrated• monolithic approach and coordinated mono-functional approach.

TOPICS-IB is under development in JAEA for integrated simulation of burning plasmas

SONIC is under development in JAEA as a SOL/Divertor simulation code

Interface between TASK and SONIC will be developed as a future work

RF - 2007-2008 plans

• Improved funding situation on the longer term

• Plasma start-up and termination • RWM theory, code development, modeling and control

options• FPP – NBI modules, code development for self consistent

simulation of the AE excitation and associated FP transport• Reorganization of the codes according to ITER ITM

strategy• Detailed description of the physics model and

mathematical algorithms employed – key issue for successful benchmarking and mutual progress!– Qualification part of V&V

EU Integrated Tokamak Modelling TF

Summary CDBM IMAGE meeting, 07

The longer term aim is not a single (transport) code but a

complete simulation environment

2008 - Start of the Gateway for IM and deployment of code platform

– Implies a complete set of data structures and associated tools– A fully operational portal/workflow configuration– Major code releases from all of Integrated Modelling Projects

2009 - Extended set of platform tools forming a predictive core physics capacity for ITER

– Production level modelling for ITER and a standard tool for current experiments– local clusters and grid

2010/11 - Whole device modelling capability including comprehensive core-edge coupling and first principles elements

– Aiming towards Broader Approach IFERC level computations

PTRANSP developments

• Predictive simulations are now being carried out with the PTRANSP code based on advances in the past 2-1/2 years

• Significant advances in the physics content will be added during the next 2-1/2 years– High-quality widely used modules for transport, equilibrium,

sources, sinks and large scale instabilities all interacting together in one code

– Comparison with experimental data facilitated by extensive data analysis infrastructure already built into TRANSP

• As a result of the effort planned for the next three years, PTRANSP will become significantly more comprehensive

• PTRANSP will serve as a bridge to high-performance SciDAC Fusion Simulation Projects
