This is a specialized version of GetDP, tailored specifically for acoustic simulation problems.

GetDP's original README is given below:

This is GetDP, a General environment for the treatment of Discrete Problems.

Building a bare-bones version of GetDP from its source code requires a C++ compiler and CMake (https://cmake.org). By default GetDP also uses the GSL (https://www.gnu.org/software/gsl) and PETSc (https://www.mcs.anl.gov/petsc), using either real or complex arithmetic. If PETSc is available, GetDP can use SLEPc (https://slepc.upv.es/) to solve eigenvalue problems. Instead of PETsc (and SLEPc), GetDP can also use a built-in set of linear solvers derived from Sparskit Version 2 (https://www-users.cs.umn.edu/~saad/) and eigensolvers from Arpack (https://www.caam.rice.edu/software/ARPACK). Sparskit and Arpack, as well GetDP's special mathematical functions require a Fortan compiler and BLAS/LAPACK.

• Launch CMake and fill-in the two top input fields (telling where the GetDP source directory is located and where you want the GetDP binary to be created).

• Click on "Add entry" and define the variable CMAKE_PREFIX_PATH, of type "PATH", pointing to the location(s) of any external package(s) (BLAS/LAPACK, etc.) installed in non-standard directories.

• Click on "Configure" and choose your compiler.

• Optionally change some configuration options (re-run "Configure" every time you change some options).

• Once you are happy with all the configuration options, click on "Generate".

• Go to the build directory and build Gmsh using your chosen compiler.

• Create a build directory, for example as a subdirectory of GetDP's source directory:

  mkdir build

• Run cmake from within the build directory, pointing to GetDP's source directory:

  cd build cmake ..

• To build and install GetDP then simply type

  make make install

• To change build options you can use "ccmake" instead of "cmake", e.g.:

  ccmake ..

  or you can specify options directly on the command line. For example, you can use

  cmake -DCMAKE_PREFIX_PATH=/opt/local ..

  to specify the location of external packages installed in non-standard directories. You can use

  cmake -DCMAKE_INSTALL_PREFIX=/opt

  to change the installation directory. Or you can use

  cmake -DENABLE_PETSC=0 -DENABLE_SPARSKIT=1 ..

  to build a version of GetDP that uses Sparskit instead of PETSc.

• You can keep multiple builds with different build options at the same time: just configure the builds in separate directories.

• To see a detailed compilation log use

  make VERBOSE=1
