From rene.gassmoeller at mailbox.org Wed Mar 1 10:28:32 2017 From: rene.gassmoeller at mailbox.org (Rene Gassmoeller) Date: Wed, 1 Mar 2017 11:28:32 -0700 Subject: [aspect-devel] ASPECT 1.5.0 released Message-ID: <35834483-f4fb-e1d6-b2e8-1b751d8abd1e@mailbox.org> We are pleased to announce the release of ASPECT 1.5.0. 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.dealii.org/ and the release is available from https://github.com/geodynamics/aspect/releases/tag/v1.5.0 This release includes the following changes: - New: Choice between different formulations for the governing equations including Boussinesq and anelastic liquid approximation. - New: Melt transport (two-phase flow). - Particles: new generators, ghost exchange, performance improvements, interpolation to fields. - New: Nondimensional material model for incompressible (using the Boussinesq approximation) and compressible computations (with ALA or TALA) for nondimensionalized problems. This can be used for benchmark problems like Blankenbach, King, etc.. - New: Optional DG method for temperature/composition. - Adiabatic conditions: rework, now includes a reference density profile. - Free surface: overhaul. - New cookbooks: continental extension, finite strain, BurnMan interface, active tracers. - New benchmarks: TanGurnis, Blankenbach, King. - New: viscoplastic material model. - Material model interface cleanup. - Assembly performance improvements. - New: memory statistics postprocessor. - New: initial topography plugins. - Many other fixes and small improvements. A complete list of changes can be found at https://aspect.dealii.org/doc/doxygen/changes_between_1_84_80_and_1_85_80.html and the release is also available from https://github.com/geodynamics/aspect/releases/tag/v1.5.0 Wolfgang Bangerth, Juliane Dannberg, Rene Gassmoeller, Timo Heister, and many other contributors. -- Rene Gassmoeller http://www.math.colostate.edu/~gassmoel/ From bangerth at tamu.edu Wed Mar 1 11:08:23 2017 From: bangerth at tamu.edu (Wolfgang Bangerth) Date: Wed, 1 Mar 2017 12:08:23 -0700 Subject: [aspect-devel] ASPECT 1.5.0 released In-Reply-To: <35834483-f4fb-e1d6-b2e8-1b751d8abd1e@mailbox.org> References: <35834483-f4fb-e1d6-b2e8-1b751d8abd1e@mailbox.org> Message-ID: On 03/01/2017 11:28 AM, Rene Gassmoeller wrote: > We are pleased to announce the release of ASPECT 1.5.0.

In fact when updating my somewhat outdated knowledge about Docker I found that several of the disadvantages I remembered seem to have been resolved in the meantime. I do not want to repeat my arguments on github, so please have a look over there when you are interested in the topic (you can also subscribe to the discussion on that page to get notifications about the progress), but I think that the Docker container might really be an alternative to users who: 1. have used a different modelling software before, have set up their desktop environment to their liking, and would like to try ASPECT, but do not want to spend the time to get ASPECT to compile or 2. want to use ASPECT on a regular basis, and do not need many modifications, but have serious trouble installing ASPECT or its dependencies due to a unusual system (I remember spending a day with OpenSUSE a while back). In both of these cases a docker container just feels superior to a virtual machine. For tutorials I still think Docker containers leave more room for technical problems during the tutorial than virtual machines, but I can see from an organizer's point of view that building and modifying a docker container is much more efficient than a virtual machine (consider though that an ASPECT docker container would use around 2-3 GB of space as well, not significantly less than a VM). Anyway, I updated ASPECT's docker container (available under https://hub.docker.com/r/gassmoeller/aspect/) and added some documentation in the above mentioned pull request on how to use it. I would be happy about feedback! Best, Rene On 02/07/2017 09:45 AM, Louise Kellogg wrote: > Thanks Timo, I have used VMs but am new to docker.

My impression is that VMs work extremely well in tutorials by giving everyone a guaranteed working system, but it can be a bit of a barrier for people to transition to using the software for research on their own after the tutorial. My impression is that containers would help with this because the use environment can be the same during and after the tutorials. On the other hand, your comment suggests that VMs would be better at assuring success during the tutorial itself. >> I don't see any advantage in docker for transitioning to using the >> software for research.

I don't think I have intuition. Given the fact that both have been developed for (among other applications) and tested with finite element problems, I would imagine that there is no fundamental, asymptotic difference between the two of them. I wouldn't be surprised if there is a difference of a factor of two or three in run times, memory consumption, etc, but I would be surprised if there was a factor of ten. It would be interesting to see a comparison, just so we gain some intuition. Both are direct solvers and so will likely yield the same accuracy. In that sense, neither is going to be "better" than the other.

You can also specify them during the configuration steps. To check the configuration options in Trilinos, for example, see the file CMakeCache.txt in the build directory. If you are using the default compilers installed on your system for C++ and mpi, it is possible that these defaults changed at some point when you updated your system packages. If this is the case, Trilinos and p4est could be using different compilers than deal.ii. Although a bit time consuming, it might be worth recompiling Trilinos and p4est before rebuilding deal.ii.

Does this means that all the dependencies (p4est, dealii, trilinos) and Aspect have to be compiled with the same system state, same compilers? but that does not make sense to me from the fact that one can recompile Aspect at any time (for example to switch from debug to optimized).

I thought that it would be easier to write a script for ParaView, but from now on I'll definitely rely on ASPECT to output data like this directly. I still want to use ParaView for flow field visuals etc., so it was a bit scary to see 200-600 K discrepancies in the average temperature. However, it seems like increasing the mesh refinement will improve things. These new graphs are with the initial global refinement set to 5. The error indicator is highest near the surface so that could be the main issue here.

Correct. Internally, ASPECT uses a piecewise quadratic representation of data. However, because of file format limitations, we only output a piecewise linear representation of data. > 1.

Paraview or Visit are good for visualizing fields, but not for extracting summary information. That's what the ASPECT postprocessors are there for that have access to the internal representation of data. > 2. The data that is put in the Paraview *.vtk file is truncated.

That is true for the .vtk file format. But the .vtu file format we use by default actually provides 16 digits of accuracy.

I also wrote a visualization plugin that outputs if material is behaving plastically or viscously. Currently the way it works is I have a function named "viscosity_ratio" in my material model that re-evaluates the viscous and plastic components of viscosity the same way as in the evaluate function, and returns their ratio. But the problem is - every time I want to change something in the formulas, I have to change it in 2 places, which is error-prone. So I wanted to change it so that it calls evaluate instead of re-calculating the viscosity, but the problem is - the functions take 2 different types of input. I'm guessing I would have to make a MaterialModelInputs vector inside the viscosity_ratio function first to then use it as input for evaluate function? Should I be doing it through a FEValues object? In general, am I thinking in the right direction? Maybe there is an example of this already implemented in some existing plug-in (I couldn't find any)? Or maybe there is an easier way to implement this? Any advice would be appreciated. Best regards, Lev Karatun. -------------- next part -------------- An HTML attachment was scrubbed...

Generate an AdditionalMaterialOutputs that contains a bool or int or something for each quadrature point. You can then query this information, example: melt.cc 2. Create a function inside your material model that your postprocessor calls. For this you need to do a dynamic_cast to that specific type of material model. This allows you to query whatever function you want. Example: melt.cc and melt_statistics.cc 3. We introduce something more generic into the material model interface to report something like "int local_material_type" in each quadrature point and generate visualization plugins. This is potentially useful for different plugins. 4. You could create a compositional field that represents this information (by using reaction terms in the material model maybe?)
