cffview

A command-line tool for inspecting Ansys Fluent .cas.h5 / .msh.h5 files without opening Fluent.

• Read solver settings, materials, boundary conditions, discretisation schemes, and more directly from the HDF5 file.
• Visualise the mesh with PyVista.

Installation

PyPI

pip install cffview

From source

git clone https://github.com/preamer/cffview.git
cd cffview
pip install .

Usage

Important

Only tested with Ansys Fluent 25R2!

cffview <file> [options]

Options

Option	Description
--version	Print the Fluent version of file
--extract	Dump raw Scheme settings to general.scm and boundary.scm
--mesh, --showmesh	Visualise the mesh interactively with PyVista
--solver	Solver type, time, dimension, precision, turbulence model, energy, radiation, gravity
--mat, --materials	Material properties
--bd, --boundary	Boundary condition settings
--ne, --named-expressions	Named expressions
--disc	Discretisation schemes and relaxation factors
--rd, --report-definitions	Report definitions
--plotsets	Plot sets
--monitorsets	Monitor sets
--residuals	Residual settings
--iter	Iteration / time-step settings
--contours	Graphics contours settings
--vectors	Graphics vectors settings
--xy, --xy-plot	Graphics xy-plot settings
--save	Save the output to <file>.json
--plot	Plot the outfile with matplotlib

Multiple flags can be combined freely. Case settings flags (--solver, --mat, etc.) apply to .cas.h5 files only.

Examples

# Show all settings and save to JSON
cffview case.cas.h5 --save

# Show solver configuration and boundary conditions
cffview case.cas.h5 --solver --bd

# Visualise the mesh
cffview case.cas.h5 --showmesh
cffview mesh.msh.h5 --showmesh

# Check the Fluent version of file
cffview case.cas.h5 --version

# Extract raw Scheme strings for manual inspection
cffview case.cas.h5 --extract
