Integrating NX Expressions into FloEFD for boundary conditions, mesh settings, and other parameters can be challenging. Here's a summary of the current approach and limitations, along with possible workarounds.
Currently, you can use NX Expressions in FloEFD by creating Equation Goals, provided the expressions are unitless. However, one key limitation is that Equation Goals can depend on the part number. If you save the model under a new part number, the Equation Goal may fail to update, which can disrupt your setup. Additionally, unlike geometry references in FloEFD that update automatically, Equation Goal references are static and do not adjust with changes in part names.
To address these issues, consider defining parameters directly within FloEFD rather than relying on NX Expressions. This method can help avoid problems related to part number changes. When using CAD templates for new parts, FloEFD might not automatically recognize new parts as replacements in existing analyses, complicating the setup. For more advanced management, exploring FloEFD and NX APIs to handle renaming through scripts could be a viable solution.
