I am currently wroking on some simple beam models and i want to make some parametric studies by changing the size of the model. I was wondering if there is any script or a python code that i can use to automize this proces and not to create the model angain from the begining. Is it possible to run a model of a size length (for example 4m and then with the help of a script to change it at 6m and than it can continue to simulate that new model)? can this be done automatically.

I am eager to get some insights and I thank anyone who can help !
