Hi, I finished characterizing my model, and now I should insert forces and constraints but being my first analysis I have difficulties could someone help me step by step?
The model is a helicopter blade, i should enter the rotation, a distributed force, a moment and the force of gravity.
Than you.
Hi @mirko094,
What do you mean by "characterizing" your model exactly? Material properties and mesh?
And what is the goal of the simulation?
Hi negativevolume thank you for the interest. Yes ,I created the mesh and applied materials and properties. The goals are static analysis (Linear/non Linear) and modal analysis.Before starting the analyzes, I would need to check the model to see if it is well done. I would need help because the company where I do my thesis work has abandoned me for the moment due to the covid, and I should do the analyzes before the end of May to be able to graduate in the next session.
you need to do the analysis in two steps in Ls-Dyna:
1st step : Preloading of gravity , moment : write dynain file output
2nd step : use the dynain as input & proceed with Application of rotation.
share your model on geardyn.1@gmail.com
i will try to help you out
