When exporting to EnSight, you can choose to export the data associated with a single data file, or you can export the data associated with multiple files that were generated by a transient solution.
To export the solution data from a single data file, read in the case and data file and open the Export dialog box.
File → Export → Solution Data...
Then perform the following steps in the Export dialog box:
Select EnSight Case Gold from the File Type drop-down list.
Select the Location from which the values of scalar functions are to be taken. If you specify the data Location as Node, then the data values at the node points are exported. If you choose Cell Center, then the data values from the cell centers are exported. For boundary faces, it is the face center values that are exported when the Cell Center option is selected.
Specify the format of the file by selecting either Binary or ASCII from the Format list. The advantage of the binary format is that it takes less time to load the exported files into EnSight.
(optional) Select the Cell Zones from which you want data exported (you must select at least one zone). By default, all of the cell zones are selected.
(optional) Select the Interior Zone Surfaces from which you want data exported. By default, the data being exported is taken from the entire ANSYS Fluent domain. The Interior Zone Surfaces selection list allows you to also specify that the data be taken from selected zone surfaces whose Type is identified as interior in the Boundary Conditions task page.
Select the scalars you want to write from the Quantities selection list.
Click the Select File dialog box, which you can use to save a file that contains the specified variable data for the specified cell zones, the specified interior zone surfaces, and all of the boundary zones.button to open the
To export solution data associated with multiple files that were generated by a transient solution, you must first make sure that the following criteria are met:
All of the relevant case and data files must be in the working folder.
The data files must be separated by a consistent number of time steps.
Next, enter the following text command in the console:
Then, enter responses to the following prompts in the console:
EnSight Case Gold file name
Enter the name you want assigned to the exported files.
Case / Data file selection by base name?
yes if the case and data
files share a “base name” (that is, a common initial
string of characters). The alphanumeric order of the full names must
correspond to the order in which the files were created. You will
then be prompted to enter the base name at the
Data file base name prompt that follows. For example,
with a set of files named
so on, enter
elbow- for the base name.
no if you have created an ASCII
file in the working folder that lists the names of the data files
in order of when they were created. The file should list one data
file name per line. You will then be prompted to enter the name of
this file at the
Provide the file name which contains
the data file names prompt that follows. Note that you
must include the file extension if any in your entry at the prompt.
Specify Skip Value
Enter an integer value to specify the number of files you want to
skip in between exporting files from the sequence. For example, enter
1 to export every other file, enter
2 to export every third file, and so on.
yes if you want to export the data
values from the cell centers (or face center values, for boundary
no if you want
to export the data values from the node points.
Write separate file for each time step
for each variable?
yes if you want separate EnSight Case Gold files written for each
time step. Otherwise, all of the data for the
.vel files will be combined into a
single file for each.
Write in binary format?
yes to write the files in binary
format. Otherwise, they will be written in ASCII format. The advantage
of the binary format is that it takes less time to load the exported
files into EnSight.
Specify Data File Frequency
Enter the number of time steps between the data files being exported.
Separate case file for each time step?
no if all the data files
were generated from the same case file (that is, the simulation involved
a static mesh). Note that the name of the case file must be the same
(not including the extension) as the name of the first data file in
yes if the
data files were generated from the different case files (that is,
the simulation involved a sliding or dynamic mesh). Note that the
names of the case files must be the same (not including the extension)
as the names of the corresponding data files.
Read the case file?
no if the first (or only, for
a static mesh) case file is already in memory.
yes if the first (or only, for a static mesh) case file
is not already in memory.
cell zone id/name(1)
Enter the name or ID of any cell zone from which you want data exported. By default, the data being exported is taken from the entire ANSYS Fluent domain. After you specify the first cell zone, you will be prompted to specify the second one, and so on, until you press Enter without typing any characters.
Interior Zone Surfaces(1)
Enter the name of any interior zone surface from which you want data exported. By default, the data being exported is taken from the entire ANSYS Fluent domain. This prompt allows you to also specify that the data be taken from selected zone surfaces whose Type is identified as interior in the Boundary Conditions task page. After you specify the first interior zone surface, you will be prompted to specify the second one, and so on, until you press Enter without typing any characters.
EnSight Case Gold scalar(1) else q to
Enter in the first scalar quantity
you want exported. You can press the Enter key to
print a list of available scalar quantities in the console. After
you enter the first quantity, you will be prompted to enter the second
quantity, and so on, until you enter
EnSight Case Gold files will then be written.
When exporting to EnSight Case Gold, files will be created with the following four formats:
A geometry file (for example,
file.geo) containing the coordinates and connectivity information.
A velocity file (for example,
file.vel) containing the velocity.
A scalar file (for example,
file.scl1) for each selected variable or function.
An EnSight case file (for example,
file.encas) that contains details about the other exported
For non-stationary reference zones, all the velocities are exported to EnSight as velocities relative to the selected reference zone. See the informational note in Data Explorer Files for further details.
ANSYS Fluent supports exporting polyhedral data to EnSight.
You also have the option of exporting data at specified intervals during a transient calculation through the Automatic Export dialog box. For details, see Exporting Data During a Transient Calculation.
