8.15.9. Ansys FENSAP-ICE Files

CFD-Post can load grid (*.grid) and solution (*.soln, *.droplet, *.crystal, *.swimsol) files from FENSAP-ICE. A View Set-up File (*.fsp) can also be used to specify a list of domains, grids, and solutions over a single time step or multiple iterations.

When opened through a FENSAP-ICE Workbench component, or from the FENSAP-ICE graphical environment, CFD-Post is launched through a View Set-up File (*.fsp):

  • Upon launching a computation, the FENSAP-ICE project manager will set-up a cfdpost.fsp file in the run directory. This file contains references to the most common output files in this folder.

  • Using the View action, with CFD-Post selected as post-processor, a .cmd_post.fsp file is created, and will contain the specific files selected for the view action.

8.15.9.1. Grid Files

A grid file can be loaded in CFD-Post by selecting a *.grid file, or via a View Set-up File (*.fsp). Both formats (Airflow grid and C3D Solid grid) are supported.


Note:  If the file name does not comply with the file extension, the file can also be loaded using the All files (*) option, and the type of file will be auto-detected.


All volumes and boundary zones from the grid file will be loaded. The FENSAP-ICE boundary condition numeric identifiers will show up as zone labels such as BC_1000, BC_2000, BC_2001.

8.15.9.2. Solution Files

The recognized solution file extensions are: *.soln (FENSAP Airflow), *.droplet, *.crystal (DROP3D droplet impingement). A solution file must be read alongside a grid file. For example, alongside a *.soln file, a *.grid file is needed.

A View Set-up File enables you to specify a pair of grid and solution files, of any name and disk location.

8.15.9.3. Solution Files - Icing

The recognized icing solution file extension is *.swimsol. The icing surface grid (*.map.grid) must be alongside the *.swimsol file.

A View Set-up File enables you to specify a pair of grid and solution files, of any name and disk location.


Note:  The icing solution is mapped on a surface grid.


8.15.9.4. View Set-up File

A view set-up file has the extension .fsp, and enables you to define a list of domains. For each domain, you can specify a single, or a list of, grid and solution files.

Domain definition syntax is as follows:

domain=DomainName
grid=GridFileList
soln=SolutionFileList

A .fsp file can contain multiple domains, with each having a different name. The grid and solution file list can be a single filename, a list of filenames separated by a comma, or a filename with a wildcard (for example, grid.*.disp, soln.0000??). A single grid can be used with multiple solutions, or multiple grids can be used with multiple solutions, however, the two lists must be of the same length, the grid/solution of each index will be loaded as a pair.


Note:  All filenames are relative to the view set-up file directory.


8.15.9.4.1. Examples

Single grid with one solution:

domain=Air
grid=../naca0012
soln=soln

Two domains, each with a grid and solution pair:

domain=row01
grid=../grid.row01
soln=soln.row01
domain=row02
grid=../grid.row02
soln=soln.row02

Multiple domains, grid only:

domain=row01
grid=TurboMeshing/row1/grid
domain=row02
grid=TurboMeshing/row2/grid
domain=row03
grid=TurboMeshing/row3/grid

Ice solution on map.grid and ice.grid:

domain=map-swimsol
grid=map.grid
soln=swimsol
domain=ice-swimsol
grid=ice.grid
soln=swimsol

Multiple numbered solutions:

domain=Air
grid=../naca0012
soln=soln.000005,soln.000010,soln.000015,soln.000020

Multiple grids and solution

domain=Remeshing
grid=../naca0012,grid.disp.000002,grid.disp.000003
soln=soln.000001,soln.000002,soln.000003

Note:  soln.000001 will be loaded with ../naca0012, soln.000002 with grid.disp.000002, and so on.


8.15.9.5. Limitations

  • Grids with element groups defining materials or subdomains are loaded as a single domain. Material identifiers cannot be viewed with CFD-Post.

  • Facet-based solution files (hflux.dat and surface.dat) are not supported. The equivalent nodal solution is available through the airflow solution file (*.soln)

  • Boundary profiles (timebc.dat) are not supported. They can be viewed with the Viewmerical tool, included with FENSAP-ICE. For more details, see Post-Processing in the Ansys FENSAP-ICE User Manual.
