In this section we shall describe several test cases supplied with the OpenFOAM
distribution. The intention is to provide example cases, including those
in the tutorials in 2 of the User Guide, for every standard solver. The
examples are designed to introduce certain tools and features of OpenFOAM, e.g.
within pre-/post-processing, numerical schemes, algorithms. They also
provide a means for validation of solvers although that is not their principal
function.
Each example contains a description of the problem: the geometry, initial and
boundary conditions, a brief description of the equations being solved, models
used, and physical properties required. The solution domain is selected which
may be a portion of the original geometry, e.g. if we introduce symmetry
planes. The method of meshing, usually blockMesh, is specified; of course
the user can simply view the mesh since every example is distributed
with the polyMesh directory containing the data files that describe the
mesh.
The examples coexist with the tutorials in the tutorials subdirectory of the
OpenFOAM installation. They are organised into a set of subdirectories by solver, e.g.
all the icoFoam cases are stored within a subdirectory icoFoam. Before running a
particular example, the user is urged to copy it into their user account. We
recommend that the user stores all OpenFOAM cases in a directory we recommend
that the tutorials are copied into a directory $OpenFOAM_RUN. If this directory
structure has not yet been created in the user’s account, it can be created with
mkdir -p $OpenFOAM_RUN
The tutorials can then be copied into this directory with
