ENRICO can be configured and compiled in an arbitrary build directory. However, at configure time, you must point to the location of the Nek5000 input deck using the -DUSR_LOC flag. Here is a sample workflow, for the compiling the tests/singlerod/short/ case:

1. Create and enter a build directory anywhere. For example:

  $ mkdir tests/singlerod/short/build
  $ cd tests/singlerod/short/build

2. Enter the build directory and run CMake, using USR_LOC to specify the location of the Nek5000 input deck:

  $ CC=mpicc CXX=mpicxx FC=mpif90 cmake -DUSR_LOC=../ ../../../../`

3. Make it:

  $ make -j4 enrico

In a given case directory, you may also compile coupled and single-physics libraries without a driver. The available targets are:

• enrico: The ENRICO executable
• libopenmc: The OpenMC library
• libnek5000: The Nek5000 library

Nek5000 provides several utilities for working with mesh data. These may be compiled using the following targets:

• genmap: The Nek5000 tool for mesh partitioning (generates a .map file)
• genbox: The Nek5000 tool for generating a simple box mesh (generates a .box file)
