Solution file output settings
Output file format
| Value | What it does | When to use it |
|---|---|---|
| none | Outputs no files. | |
| vtk default | Outputs in VTK HDF format (.vtkhdf) for reading into ParaView. The .vtkhdf output format requires ParaView 6.1.1 or later. | |
| ensight | Writes the volume solution as EnSight files with VTK's EnSight writer, one set per output cycle. Surface output is still written as VTK HDF. | For post-processing in EnSight. |
| fwensight | Writes the same VTK HDF output as | |
| native | Writes each volume variable to its own HDF5 file per output cycle, with an index file of external links to them. Surface output is still written as VTK HDF. |
Variables to output on surfaces
Variables to output in volume
ParaView Catalyst Python scripts, run on the volume solution each time it is written. Paths are passed to Catalyst as written, so a relative path is taken from the directory the run is started in.
List of stl files for FWH surface interpolation
Record impermeable FWH data on every wall: the pressure and, for viscous equations, the wall shear stress. On a mesh that overset hole cutting can blank, each face is also flagged active or inactive, so a wall covered by another mesh does not radiate.

Output precision
| Value | What it does | When to use it |
|---|---|---|
| single default | 32-bit floating-point field values. The solver writes field data at this precision. | The default. |
| double | Accepted, but not read by the solver: field data is written in single precision whatever is set. |
Retain the local->global node map so VTKHDF output can stitch partitions together without a clean-to-grid filter
Stamp VTKHDF output steps with the solver cycle number instead of physical time. Every step of a steady run carries the same physical time, so the default leaves the appended steps indistinguishable to a viewer; the cycle number makes them steppable
Emit a one-cell-deep ghost layer in the VTKHDF volume output: the partition halo cells the solver already exchanges, marked DUPLICATECELL, so filters that interpolate cell data to points (isosurfaces, for instance) are correct across partition interfaces instead of showing a seam
