ACUSOLVE Interface

Solver AcuSolve
Type of mesh unstructured mesh
Dimension 3D



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).

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: Select "Done" to perform the translation of the domain file to the ACUSOLVE files as stated above.
