Altair Hyperworks 2022.1 Inertia Relief Analysis with Optistruct (OST-1030)

Hey,
In this video I will take a closer look on inertia relief analysis, a pretty common type of analysis for example in the aerospace industry. These are helpful links to dive deeper into this topic:

All the best to you :) Keep on learning!

hi, how can i check the unit of load of a model I imported but already set it up, thank you

[@ManuelRamsaier]

The thing is, Hyperworks will not require you to pick any unit for loads. Just the units should be consistent if you want to have any reasonable output. So, the best opiton is to check if the model has material cards, because if you know how the Young's Module and the density is specified, you can guess the units. Take for example: 210000 an E for steel - you know then the unit for force is quite likely Newton and the length unit is mm. But if you don't know about the lenght scale, the force unit cannot be extracted as N/mm and kN/m are the same values for E.
