Hi everyone! 👋

StruSoft just released a new Simplex web application called Simplex Foundation. 🚀 Over the last few months, we have also created a Grasshopper package for it. 🦗  
I’d like to share two examples with you:

- The first illustrates how to use the Simplex Foundation API with the FEM-Design API.

- The second example shows how to use an Excel file containing support reaction forces and how to load it into Simplex and run the calculations.

I hope you will enjoy it! 🙂

**Note**

1. Please install the most recent version of the LunchBox package.
2. You need a Simplex account and a license to run the analysis. To install the tool, just open the Grasshopper script and `PackageManager` will do the trick 🧙
