Geom Module Unit Tests¶

Tests for the mesh geometry infrastructure in src/Geom/. All C++ tests use doctest. MPI-aware tests are registered with CTest at multiple process counts.

Building and Running ¶

# Build all Geom C++ test executables
cmake --build build -t geom_unit_tests -j8

# Run every Geom CTest
ctest --test-dir build -R geom_ --output-on-failure

# Run a single suite
ctest --test-dir build -R geom_elements --output-on-failure

Element Types (test_Elements.cpp)¶

See also: test_Elements.cpp

Serial-only tests for element geometry definitions, node counts, and shape function evaluation.

Quadrature Rules (test_Quadrature.cpp)¶

See also: test_Quadrature.cpp

Serial-only tests for Gaussian quadrature points and weights on standard elements (triangles, quads, tetrahedra, hexahedra, prisms, pyramids).

Mesh Index Conversion (test_MeshIndexConversion.cpp)¶

See also: test_MeshIndexConversion.cpp

MPI-parallel tests verifying local-to-global and global-to-local index conversions on partitioned meshes.

Mesh Pipeline (test_MeshPipeline.cpp)¶

See also: test_MeshPipeline.cpp

MPI-parallel end-to-end tests for the mesh construction pipeline: reading, partitioning, ghost creation, and boundary extraction.

Distributed Mesh I/O (test_MeshDistributedRead.cpp)¶

See also: test_MeshDistributedRead.cpp

MPI-parallel tests for reading CGNS mesh files in parallel and redistributing across different partition counts.
