2.19. Ansys CFX-Pre Node

The Ansys CFX-Pre node is available from the Process chain elements > Integrations folder in the Modules pane and allows Ansys CFX-Pre to be used within an optiSLang workflow. A typical application would be to load a mesh file generated by an upstream meshing node and generate a CFX definition file for use by a downstream Ansys CFX-Solver node.

This node is a beta feature. To use it, ensure beta features are enabled.

You can also use two other CFX nodes:

Setup

The reference file must be a CFX-Pre session (.pre) file.

Typically, this would be generated by recording a session file in CFX-Pre. For details, see CFX-Pre Session Menu in the CFX-Pre User’s Guide. Some manual editing of the session file may be required, for example to adjust file paths.

Prior to use, ensure that the session file runs successfully and generates a definition file.

Parameters

There are no input parameters.

Responses

There are no output parameters.

Parallelization

Design points may be processed concurrently using the Additional Options >Maximum in parallel option. The Advanced Options >Designs per execution option is also supported, although its use does not currently provide any performance advantage.

Settings

This node provides the following settings:

Name Default Value Description

Set Custom CFX Root Directory False Specifies whether a custom CFX root directory will be set. Unless enabled, the auto-detected default value shown in CFX Root Directory will be used.

CFX Root Directory

CFX root directory if found in same installation as optiSLang.

Name	Default Value	Description
Set Custom CFX Root Directory	False	Specifies whether a custom CFX root directory will be set. Unless enabled, the auto-detected default value shown in CFX Root Directory will be used.
CFX Root Directory	CFX root directory if found in same installation as optiSLang.	Allows you to specify the root directory of the CFX installation. In most cases where CFX and optiSLang are present in the same installation, the value of this setting will be pre-populated. You only need to change the CFX root directory if using a CFX installation in a different location. Environment variables can be used in the path string to improve project portability. The patterns `%VAR%` and `${VAR}` will be substituted with variable values, irrespective of the operating system.
Custom Arguments	Empty	Optional. Allows you to create additional command line arguments used for each run of CFX-Pre, for example, to specify an additional CFX-Pre session file. For details of these options, see Starting the CFX-Solver from the Command Line in the CFX-Solver Manager User's Guide.
