Workshop Advanced usage of viiaPackage

This workshop is held on 29th January 2021 and 5th February 2021 by Vaibhav Raghavan and Aivaras Aukselis.

Note

Experience using the viiaPackage, DIANA software and python are required for this workshop. Checkout the beginners course for using the viiaPackage here: ‘Workshop basic viiaPackage’.

Aim of the workshop:

• More aware of features of the viiaPackage and fem-package(secondary) with aspects to strengthening, result handling and modelling for NLTH;

• Aware of some workarounds to be used as a last resort;

• Tips and tricks to make your workflow faster.

This workshop aims at showing the architecture of the code and how to interact with it. The reason to show workarounds is to show how to handle the object schema and how that can help you to solve your specific problem.
