|Type of mesh
The translator creates the following ACUSOLVE files:
The translator writes the ACUSOLVE files using an unstructured
domain file, a boundary conditions file and a parameters file (acusolve.par).
ACUSOLVE configuration file
ACUSOLVE input file
MESH.DIR/filename.crd: Computational mesh
MESH.DIR/filename.*.cnn: Cell connectivity files for
each cell group/topology
MESH.DIR/filename.*.ebc: Element boundary condition
file for each boundary group/topology
MESH.DIR/filename.*.nbc: Nodal boundary condition
file for each boundary group
MESH.DIR/filename.pbc: Periodic boundary
condition node pairs
filename.*.nic: Option to create .nic files for Optimesh
Setting the ACUSOLVE Parameters and Options
To create the ACUSOLVE input files, select "ACUSOLVE" in the "Output >
Select solver" menu. Click on the icon "Edit parameters" which brings up
ACUSOLVE Solver parameters window.
Within this panel, solver options are specified, such as problem type,
turbulence models, material models, solution strategy, etc.
New material models can be created by selecting "Create new" under the
Material Model heading. Within a material model, select the material
model name and specify fluid or solid. Select the property to be specified
and enter the appropriate values.
Once the desired parameters and properties are specified select "Accept"
at the bottom of the panel. This writes the acusolve.par file
to be used in the translation process. This is the minimum that needs
to be performed to enable the ACUSOLVE files to be written.
If the equations of the model were changed in the Problem Description
panel when first setting the solver parameters, the Solution Wizard under
Solution Strategy should be run. The parameters panel should be re-opened,
and select the '+' next to Solution Strategy and select "Solution Wizard"
to open the "Solution Wizard" panel.
Make any desired changes to the settings and select "Accept" at the
bottom of the panel. This re-saves the acusolve.par file.
Re-open the parameters panel and go back to the Solution Wizard panel.
Select "Run Wizard" to reset the solution strategy parameters according
to the new settings. Select "Accept" again at the bottom of the panel,
as it is necessary to save the acusolve.par file immediately before
and after running the Solution Wizard.
Setting Boundary Conditions
To set boundary conditions, click on the icon "Boundary conditions" from the Output menu.
The available element types
are Volumes, Surfaces, Edges, Nodes, and Mixed/Unknown. For the families
under Volumes, select the appropriate material model and whether it is
fluid or solid. NOTE: As a minumum, the material model for each Volume
family should be specified. For Surfaces, Simple BCs can be specified
as well as radiation parameters, etc.
When all desired boundary conditions have been specified, select "Accept"
at the bottom of the panel.
Creating the ACUSOLVE Files
Click on the icon "Write input" from the Ouput menu.
Select an existing unstructured domain
file from the list of available filesi, then click "open".
A window will then open with the different options for the ACUSOLVE input:
Give the prefix for the ACUSOLVE file names (problem name)
- Specify the ACUSOLVE problem directory
Give the name of the parameter file
Give the name of the boundary condition file
Option to give a scaling factor for each direction (default is 1.0) if
necessary to convert dimensions to meters
Option to specify the user auxiliary script, if applicable
- Option to write a .inp file
Option to create .nic files for Optimesh
Option to write internal walls
Select "Done" to perform the translation of the domain file to the ACUSOLVE
files as stated above.
This interface is only written for 3D models.
