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

pip install cffview

Build from source

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

Usage

cffview <file> [options]

Options

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

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

Examples

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

# Show all settings and save to JSON
cffview case.cas.h5 --solver --mat --bd --ne --disc --rd --iter --save

# Visualise the mesh (.cas.h5 and .msh.h5 both supported)
cffview case.cas.h5 --showmesh
cffview mesh.msh.h5 --showmesh

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

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