ANSYS Workbench was designed to be a parametric and persistent platform so that you could easily perform design studies and really get into simulation driven product development. Tools like DX can help you drive those parameters, but first, you need to parameterize your model.
You can parameterize the physics or even the meshing, but being able to parameterize the CAD using our bi-directional CAD interfaces is a real ANSYS Advantage.
Earlier posts have showed you how to parameterize DesignModeler, Spaceclaim, Creo Parametric and Catia. Here is a quick demo (made by Richard Mitchell, UK Sales Support Manager) showing you how to parameterize and create named selections in NX.
To create a Named Selection in NX:
- Go to the ANSYS tab (after installing the NX Workbench CAD interface)
- Click on the “NS Manager” in the NX-ANSYS ribbon
- Select the entities to name, hit [OK]
- Enter a name (keep in mind that you can use a filter prefix such as the default “NS_” if you don’t want all your publications to be seen as Named Selections in Workbench, hit [OK].
- The new named selection is added to the “ANSYS Named Selection Manager” in NX, hit [Close]
To create a parameter in NX:
- Go to “Tools” tab, Expressions
- Name an expression (again, many experts like to use the prefix “DS_” so that can filter for it later)
- Set the “formula” for the expression equal to the value you want for the parameter
- Use the “expression” as a parameter in your model design (such as by browsing to the right place in the model history, choosing “Edit Parameters”, and replacing a dimension)
When you get to Workbench, you need to make sure that you turn on the Basic Geometry Options for parameters and Named Selections and that the filters are appropriate (or cleared to bring in all the parameters or Named Selections).
Once a model is parameterized, it can be driven by adding rows to the table of design points, or using a tools like ANSYS DesignXplorer with algorithms that can be used to generate design points or drive the design optimization process.
