Notes
- These are not the advised, recommended or even suggested build instructions.
I am simply reporting what worked for me, on my laptop, running
Ubuntu 22.04.4 LTS (Jammy Jellyfish). - I think these are all of the packages that I am using that are required to follow along:
sudo apt-get update sudo apt-get install -y make cmake sudo apt-get install -y make cmake git-all sudo apt-get install -y gcc g++ gfortran sudo apt-get install -y build-essential libopenmpi-dev openmpi-bin sudo apt-get install -y m4 sudo apt-get install -y vim - I’m doing this in a quad core laptop, so all make’s are with
-j2. If you have more resources available, use them. - I initially tried ascent
developwith vtk-mv2.1.0and conduitv0.8.8.
I was able to compile successfully, but the code hits a runtime error due to
a missing vtk-m worklet library.
Without further ado, let’s open up a temporary directory and get started.
rm -rf tmp.build.deps
mkdir tmp.build.deps && cd tmp.build.deps

We are done building dependencies. I always super-build MFIX-Exa, so the csg-eb lib gets build right along with it. But, it’s probably not a bad idea to go ahead and build the standalone lib now too, just in case.

mkdir -p $CSG_LIB_DIR

Running a job
I’ll use bench05 as a simple test of the executable.
First let’s make sure it runs “as-is”
cd ../benchmarks/05-cyl-fluidbed/Size0001/
ln -s ../../../build.deps/mfix
mpirun -np 1 ./mfix inputs
You should see a bunch of screen output that ends with AMReX (id) finalized.
Unfortunately, this doesn’t test any of the dependencies that we just built against.
Use your text editor of choice to modify the inputs file to
-
use multiple grids:
The grid size is set to the maximum,1024in each direction. And the
entire domain size is justamr.n_cell = 20 5 5. Let’s set
amr.max_grid_size_x = 10so that the problem is decomposed onto two grids. -
use the csg library:
Fortunately, there is already a csg file of the cylindrical EB, we just need
to enable it. Just comment in thegeometry_filenamekeyword and comment out,
or delete, the amrex-native EB keywords,mfix.geometry_filename = "geometry.csg" #mfix.geometry = "cylinder" #cylinder.internal_flow = true #cylinder.radius = 0.00045 #cylinder.height = -1.0 #cylinder.direction = 0 #cylinder.center = 0.0020 0.0005 0.0005 -
use the hypre linear solvers:
This problem is simple, so amrex’s defaultbicgbottom solvers work fine, but
let’s offload to hypre just to test the build,mac_proj.bottom_solver = hypre nodal_proj.bottom_solver = hypre -
use ascent visualization:
Add these input keywordsmfix.ascent_int = 10 ascent.actions = "ascent_actions.yaml"and create a simple ascent pipeline named
ascent_actions.yaml. Here’s a simple one to
visualize the particles looks like- action: "add_scenes" scenes: s1: plots: p1: type: "pseudocolor" field: "velz" points: radius: 50.0e-6 min_value: -0.001 max_value: 0.001 color_table: name: "Default" renders: r1: image_width: 360 image_height: 720 image_prefix: "vis_p_velz_%06d" camera: position: [ 0.002, 0.0005, 0.0087] look_at: [ 0.002, 0.0005, 0.0005] up: [1, 0, 0] zoom: 2.2 bg_color: [ 1.0, 1.0, 1.0] fg_color: [ 0.0, 0.0, 0.0] render_bg: "true" shading: "enabled"
Now we’re ready to re-run. This time, use two processes and let’s pipe the std out
to a screen file,
mpirun -np 2 ./mfix inputs > screen.txt
In the output you should now be able to verify that you
ran in parallel by seeing MPI initialized with 2 MPI processes- used the csg-eb library by seeing
mfix.geometry_filename: geometry.csg - if you enabled TinyProfile in the build, you should see several hypre routines being hit in the profiling at the end of the screen output, such as
HypreIJIface::run_hypre_setup()andHypreIJIface::run_hypre_solve() - ran with ascent in situ visualization by seeing the printed png files, e.g.,
