Opacities

WeakLib Opacity UnitTests

Implement Examples

• WeakLib Opacity table IO test:

  • wlReadOpacityTableTest.f90

• Interpolating on WeakLib Opacity tables:

  • wlInterpolateAb.f90 for absorptivity and emissivity table
  • wlInterpolateIso.f90 for isoenergetic scattering table
  • wlInterpolateNES.f90 for neutrino-electron scattering table
  • wlInterpolatePair.f90 for pair process table

Step-by-step instruction for obtaining the comprehensive opacities with a given profile:

1. Write the profile into the stardard format, as ProfileExample.profile.

   Keys:

   • Filename ends with .profile
   • First line of the profile gives the number of rho-T-Ye states
   • Star the data from the third line
   • Given the states in radius-density-temperature-electron fraction order
   • in unit of [Arbitrary], [g/cm^3], [K], [Dimensionless]

2. Download, link or place the WeakLib EoS table and opacity tables with the profile under a same directory.

   Keys:

   • WeakLib tables can be found at https://code.ornl.gov/astro/weaklib-tables.
   • You can create a new directory under ./Executables or any place you want to run the test.

3. Copy WriteTxtForInterpolation.sh to the same directory and run it by $./WriteTxtForInterpolation.sh

   A dataList.txt file should be generated.

   Keys:

   • Check dataList.txt to see if the files' name are all listed as profile, Eos table, opacity table

4. Next, generate the interpolating executables.

   Keys:

   • Set your compile environment by

   $source weaklib/Distributions/Workflow/SetEnvironment.sh machinename

   Replace weaklib directory and machinename as needed

   • Then go to Distributions/UnitTests/Opacities/Executables make using

   $make Interpolations

   to compile.

   • If everything works correctly, you should see four executables wlInterpolate*_machinename now.

5. Link the executables to the same directory as the tables, and run the executables:

   • Run the executables by

   $./wlInterpolateAb_machinename

   $./wlInterpolateIso_machinename

   $./wlInterpolateNES_machinename

   $./wlInterpolatePair_machinename

   • Each of the run gives a Interpolated*Output.h5 file which is the opacity rates.

6. To plot the Interpolated*Output.h5 result, use the plotInterpolatedCompactHDF.m matlab script.

   Keys:

   • Change the file directory and axis limit as needed.

Copy-To-Go Bash Script

You can copy the following code and save it as '/weaklib/unitTest.sh' and do '$source unitTest.sh'.

Note 1: it assumes you have done the table creating first and the table to test is under External/Utilities/Opacities/Bruenn85/Executables.

Note 2: change machine setting, 'summit', to the one you're running on. (Check Distributions/Workflow/SetEnvironment.sh for the options)

cd Distributions/UnitTests/Opacities/Executables
export WEAKLIB_DIR='../../../../../weaklib'
source ../../../Workflow/SetEnvironment.sh ranchuair
[ -e TableReadingLog ] && rm TableReadingLog
[ -e wl-EOS-SFHo-15-25-50.h5 ] && rm wl*.h5
[ -e InterpolatedAbOutput.h5 ] && rm Interpolated*.h5
make clobber
make all
ln -s ../../../../External/Utilities/Opacities/Bruenn85/Executables/wl*.h5 .
./wlOpacityFieldsTest_ranchuair > OpacityFieldsTestLog
./wlReadOpacityTableTest_ranchuair > TableReadingLog
[ -e *.profile ] && rm *.profile
cp ProfileBruenn.d ProfileBruenn.profile
../WriteTxtForInterpolation.sh
./wlInterpolateAb_ranchuair
./wlInterpolateIso_ranchuair
./wlInterpolateNES_ranchuair
./wlInterpolatePair_ranchuair
./wlOpacityPerformanceTest_ranchuair

To view the result, you can use UnitTests/Opacities/plotInterpolatedCompactHDF.m and compare your plot with those examples at https://code.ornl.gov/astro/weaklib-tables/SFHo/LowRes/Example.png
