Integrated Workflows with Oasys GSA and Oasys AdSec Grasshopper Plugin

16/11/22 14:00-15:00 (GMT)

Sponsored webinar with the IStructE

In the past, engineers have been relying on manual copy-pasting of tabulated data from analysis model results to design package load inputs. With the new .NET APIs for Oasys GSA and Oasys AdSec, it has become possible to stream the data directly from analysis model to design software – and back. Here at Oasys we have made this integration fully customisable by wrapping both GSA and AdSec inside Grasshopper, making it easy for engineers to automate interoperability tasks and create better designs using data.

This webinar focuses on using Grasshopper, a visual programming interface that provides a low-level entry to engineers to start coding. We take you through the steps of setting up a typical workflow; going from an analysed GSA model with results, over to AdSec to perform detailed concrete section analysis and optimisation, and then back again to GSA with updated section modifiers.

Watch the webinar recording below.

In more detail, we show how to:

  • Create a parametric GSA model with GSA-Grasshopper plugin
  • Extract GSA model data, like Section Profile and Material Grade
  • Use AdSec-Grasshopper plugin to create concrete sections based on the GSA model’s section and adding parametrically defined rebar layout
  • Extract GSA model results and use these as input loads for the AdSec section analysis
  • Perform various optimisation steps using the plugins
  • Extract AdSec results data, like crack width sizes and secant modulus, to create GSA section modifiers based on the section design.
