# Building a Parameterized Custom Source
|
||
|
|
|
||
|
|
To run this example, you first need to compile the custom source library, which
|
||
|
|
requires headers from OpenMC. A CMakeLists.txt file has been set up for you that
|
||
|
|
will search for OpenMC and build the custom library. To build the source
|
||
|
|
library, you can run:
|
||
|
|
|
||
|
|
mkdir build && cd build
|
||
|
|
OPENMC_ROOT=<path_to_openmc_install> cmake ..
|
||
|
|
make
|
||
|
|
|
||
|
|
After this, you can build the model by running `python build_xml.py`. In the XML
|
||
|
|
files that are created, you should see a reference to build/libparameterized_source.so,
|
||
|
|
the custom source library that was built by CMake, and values in the parameters
|
||
|
|
attribute. The model is also set up with a mesh tally of the flux, so once you run
|
||
|
|
`openmc`, you will get a statepoint file with the tally results in it. Running
|
||
|
|
`python show_flux.py` will pull in the results from the statepoint file and display
|
||
|
|
them. If all worked well, you should see a ring "imprint" as well as a higher flux to
|
||
|
|
the right side (since the custom source has all particles moving in the positive x
|
||
|
|
direction).
|
||
|
|
|
||
|
|
Once built, you can edit the parameters attribute on the source to change the radius of
|
||
|
|
the sampled ring or the energy of the sampled particles.
