TPLS Mini Symposium (Keynote by Prof. Christian Ruyer-Quil & TPLS Version 2 Open source Launch)


LT2, Hudson Beare Building


Thursday, May 21, 2015 - 13:00 to 17:00

TPLS Mini-Symposium and TPLS Version 2 Opensource Launch

Including Keynote by Professor Christian Ruyer-Quil, Université de Savoie - Chambéry

Venue - LT2, Hudson Beare

All of you are cordially invited to the second open source release of the TPLS flow solver. The full programme for the day is indicated below.

TPLS is an ultra-high resolution 3D two-phase flow solver, freely available as open source. It has already been used to understand flows in several engineering applications including two-phase flows in channels, droplet evaporation and vertical counter-current flows in carbon-capture equipment. You might recollect that the first version was released around two years ago. Ever since the first launch, the solver has garnered several users in academia and industry, clocking 244 downloads to date. Highlights of the second version include:

  • The unique diffuse-interface method (Ding et al, J. Comp. Phys, 226 (2), 2078–2095) as a second choice for interface-tracking. The diffuse-interface method is particularly useful for simulating flows with contact-lines.
  • Choice of two interface tracking methods - the Level-Set Method and the Diffuse-Interface method.
  • Parallel I/O - resulting in reduced output file size and contributing to speed-up.
  • Improvised parallel performance - further optmised solvers.
  • Highly parallelisable using mixed OpenMP/MPI architecture
  • Optimised on ARCHER (> 3072 Cores);
  • Fortran coding with PETSc subroutines and parallel-NETCDF I/O

TPLS has been developed by Lennon Ó Náraigh, Dr Prashant Valluri, Dr Toni Collis, Dr David Scott, Iain Bethune and Prof Peter Spelt under the aegis of several ARCHER (previously HECToR) computer time grants and funding from EPSRC and the eCSE programme. Further information on the contributing developers and funding programmes can be found in the further information section below.
