While incredibly powerful and flexible, this approach raises questions about the reliability and maintainability of scientific models when each new problem is solved using a new script or piece of code. During this seminar we will discuss TerraFERMA, a model building framework built on the FEniCS, PETSc and SPuD libraries, that aims to increase the maintainability of models by providing a common core to all models designed using TerraFERMA’s interface. This core library allows updates to the underlying libraries to be implemented largely unseen by the user and for new functionality to be made available to all existing models without having to edit each one individually. Along with an extensive test suite, it also ensures that verifying one model provides some trust in another. We will discuss our goals in designing TerraFERMA, give a brief overview of its structure, demonstrate some examples of its use and discuss our future development goals.

Most researchers are white males, and the majority of software packages in the area are developed by all-white all-male teams. We all lose out if we accept this state. An important piece in addressing this issue is building a *community* among those who do not look like the majority. As one step towards this, we will run the Computational Methods for PDEs Summer School Colorado State University Fort Collins, CO, USA August 3-9, 2019 https://dealii.org/pdeschool-2019/ This summer school is geared toward undergraduate and graduate students with an interest in the numerical solution of partial differential equations, primarily using the finite element method. While registration is open to everyone, we will give strong preference to women and underrepresented groups. The school will run August 3-5. It precedes the "Seventh deal.II Users' and Developers' workshop" which will be held August 6-9, 2019, also in Fort Collins, Colorado. Participants of the school will get an introduction to deal.II and will then participate in the deal.II workshop where they get to further build a network of peers. Registration: For workshop and registration information, see https://dealii.org/pdeschool-2019/ Deadline for registration: May 5, 2019. Participation is capped at around 30. Travel support: A limited amount of (domestic) travel support is available courtesy of the National Science Foundation, and will be given on a first come first serve basis, with preference to undergraduate and graduate students. If you need support, please state so in your registration.

The intent of this workshop is to discuss applications and tools using deal.II, as well as future directions of the library itself. We invite proposals for talks and discussion topics by users and existing developers in the following areas: - Use cases and applications of the library. - What users think would be useful directions for the library to go into, things that are missing, and possibly getting people together who can help implement those parts. - Newer parts of the library (e.g., geometry descriptions, large parallel computations, etc.) and how these could help in your programs. A significant part of the time will be set aside for "hackathon"- or "code jam"-style sessions where people can ask questions, work on their codes with others, and receive help from experienced users. Registration: For workshop and registration information, see https://dealii.org/workshop-2019/ Deadline for registration: May 5, 2019. Participation is capped at around 60.

Louise was unwell for just a short time and it is a terrible shock for all of us that she will not be returning to lead CIG. CIG was very important to Louise and she worked very closely with the executive committee to outline her vision for the future of the organisation. We will all work very hard to see that vision delivered. Louise had asked Magali Billen and Lorraine Hwang to step in to look after CIG in the short term. We do not have details of a memorial service or means to pass on condolences to Louise’s family but will circulate any information as soon as we can.

Please note that there are substantive changes to the program, including the addition of three possible tracks for projects. The target date for submission of proposals is August 15, 2019. The announcement of the program and link to the solicitation may be found at: https://www.nsf.gov/funding/pgm_summ.jsp?pims_id=503447 A webinar will be held on Tuesday, May 14 at 2 pm EDT, with a brief overview of the program and the opportunity to ask questions. Please email swhitmey at nsf.gov by 5 pm on Friday, May 10 to enroll in the webinar. SYNOPSIS The Division of Earth Sciences (EAR) will consider proposals for the development of cyberinfrastructure (CI) for the Earth Sciences (Geoinformatics). EAR-supported geoinformatics opportunities will fit into three tracks: Catalytic track, Facility track, and Sustainability track. These tracks broadly support the lifecycle of geoinformatics resource development, from pilots (Catalytic) to broad implementation (Facility) to sunsetting and long-term sustainability (Sustainability). The GI Catalytic Track will support pilot geoinformatics development efforts that are intended to serve Earth Sciences research. The GI Facility Track will support awards for implementation and operation of a cyberinfrastructure resource relied upon by one or more Earth Science communities to address science questions. The GI Sustainability Track will support development and implementation of sustainable funding models to preserve data and software products of value to Earth Science research. -------------- next part -------------- An HTML attachment was scrubbed...

ASPECT is the Advanced Solver for Problems in Earth’s ConvecTion. It uses modern numerical methods such as adaptive mesh refinement, multigrid, and a modular software design to provide a fast, flexible, and extensible mantle convection solver. ASPECT is available from https://aspect.geodynamics.org/ and the release is available from https://geodynamics.org/cig/software/aspect/ and https://github.com/geodynamics/aspect/releases/tag/v2.1.0 This release includes the following significant changes: * New: ASPECT has a new plugin system that allows to prescribe a fixed heat flux (instead of prescribing the temperature) at the model boundaries. * New: Compositional fields can optionally be advected with the melt velocity. * New: There is now a visualization postprocessor that outputs the compaction length, the characteristic length scale of melt transport. * New: ASPECT can optionally use the Geodynamic World Builder (https://github.com/GeodynamicWorldBuilder/WorldBuilder/) to create complex initial conditions for temperature and composition. * New: ASPECT can now read in a depth-dependent vs to density conversion file, which can be used with the included tomography model plugins. * New: ASPECT can now read in a depth-dependent initial temperature from file. * New: The ‘ascii data’ and ‘function’ boundary velocity plugins now allow velocities to be specified along spherical (up, east, north) unit vectors. * New: Added a visualization plugin that directly outputs the strain rate tensor. * New: ASPECT can now call PerpleX to calculate material properties, phase amounts and compositions on-the-fly. This model is provided as a proof-of-concept; more efficient procedures are required for production runs. * New: ASPECT now outputs a dynamically generated URL based on used features to ask people to cite appropriate papers. * New: ASPECT has two visualization postprocessors which calculate and output the grain lag angle and the infinite strain axis (ISA) rotation timescale, respectively. These two quantities can be used to calculate the grain orientation lag parameter of Kaminski and Ribe (G3, 2002). * Improved: The artificial diffusion term that is added in the entropy viscosity method to the temperature and composition equations is now computed as the maximum of the physical diffusion and entropy viscosity instead of the sum. This reduces numerical diffusion for the temperature field. * New: Compositional fields can now be prescribed to a value that is computed in the material model as an additional output at every time step. * Changed: The heat flux through boundary cells is now computed using the consistent boundary flux method as described in Gresho, et al. (1987), which is much more accurate than the previously used method. * New: ASPECT can now calculate gravity anomalies in addition to the geoid. * New: ASPECT now outputs a file named original.prm in the output directory with the exact content of the parameter it got started with. * New: Added basic support for a volume-of-fluid interface tracking advection method in 2D incompressible box models. The VoF method is an efficient method to track a distinct compositional field without artificial diffusion. * New: There is now an option to output visualization data as higher order polynomials. This is an improvement in accuracy and requires less disk space than the ‘Interpolate output’ option that was available before. However the new output can only be read by ParaView version 5.5 and newer and is therefore disabled by default. * New: Several new benchmark cases were added. * Many other fixes and smaller improvements. A complete list of changes and their contributing authors can be found at https://aspect.geodynamics.org/doc/doxygen/changes_between_2_80_80_and_2_81_80.html Wolfgang Bangerth, Juliane Dannberg, Rene Gassmoeller, Timo Heister, Jacqueline Austermann, Menno Fraters, Anne Glerum, John Naliboff, and many other contributors. -------------- next part -------------- An HTML attachment was scrubbed...
