Embedding a designer in a parametric study

Chris Settanni — Wed, 29 Nov 2023 16:39:54 +0000

Many Flownex users are familiar with using the Designer to size components to meet design requirements or using parameter tables to sweep through various operating conditions. Well, what if you need to do both? You may want to know operational inputs (without building out controls) for various operating conditions.

Change boundary condition option through Script

VikramGovindarajan — Thu, 12 Oct 2023 03:30:49 +0000

How to change the value of component variables using Script has already been well described in the following link:

https://www.padtinc.com/2021/10/08/avoid-spiderwebs-with-direct-references-in-scripts/

This works for an integer or double-type variable. Is it possible to change the list variables using Script? For example, is it possible to change the "Pressure boundary condition" variable in a Boundary Condition component from "Fixed on user total value" to "Not specified" using Script?

Competitive Advantages of 1D/3D Coupled Simulation – Webinar
