Work Plans


  • Continue code improvements to CitcomS
  • Add PETSc as a solver option
  • Develop 3D spherical benchmarks in conjunction with ASPECT subgroup


  • Explore options for improving the energy solver,
  • Develop and deliver tutorials,
  • Replicate existing benchmarks; develop 3D shell benchmark
  • Improve temperature/composition stabilization scheme,
  • Add active tracers,
  • Provide better support for levelset-like compositional field,
  • Parallel benchmarking of deal.II and ASPECT to find bottlenecks,
  • Work with members of the community to get their patches into ASPECT

The group anticipates: more cookbooks, nonlinear models: more testing and bug fixing, porting to new platforms (e.g., the Bluegene/Q machine at Texas A&M and the machines at the German High Performance Computing Centers), continued work on improving the manual, new ASPECT releases, work on a second ASPECT publication detailing, among other topics, how ASPECT treats compressible models.

Past Activity

Implementing Solvers in CitcomCU and CitcomS Workshop at University of California, Davis September 16-17, 2013 to address specific avenues for furthering solver capabilities for CitcomS and CitcomCU. 

CIG Mantle and Lithospheric Dynamics Workshop, Joint with the Canadian Geophysical Union in Banff, Canada, May 4-7, 2014. Participants came together during 3 science sessions:

  • Computational Methods: Advancing the state of the art in computational modeling of mantle and lithosphere dynamics
  • Mantle Convection: New insights from mantle convection modeling: Exploring mantle dynamics from the lithosphere to the base of the mantle
  • Lithospheric Evolution: Geodynamics of lithosphere evolution: Numerical models and observational constraints

ASPECT Hackathon, May 14-23, 2014. Fourteen participants converged on Texas A&M in College Station, Texas for 10 days of code development while improving their coding skills and practices. 

Code Release: ASPECT 1.0 & 1.1. The ASPECT developers group has added many new features including performance improvements, new and improved cookbooks, an improved temperature/composition stabilization scheme and active tracers.

The Citcom development group is also working on 3D spherical benchmarking with the ASPECT group as well as other research groups around the world.  

Efforts continue in removing the Python code from CitcomS to streamline the code base, testing to ensure cookbooks work properly, updating the manual highlighting the multigrid solver, and adding PETSc as a solver option.
