That's all there is to it. Now you can analyze how the model will react to a downward force of 100 N

(approximately 10 kg dumbbell weight). If you reload, rerun, and investigate the BicepsLong force again,

you should see this:

The muscle force is obviously much larger than before, and the development is also different. It now reaches

a maximum during the movement and drops off again.

Applied forces do not have to be constant. They can change with time and other properties in the model.

Please refer to the tutorial on forces

for more details.

There are infinitely many studies that could be made using even a simple model like this one, and you are

encouraged to experiment a little or a lot. To get reliable results, however, would take at the very least an

individual definition of the muscles with a realistic strength for each of them, and a more detailed modeling

of the deltoid's origin-insertion path in the shoulder; it can be a comprehensive job to define a realistic body

model which is exactly why most users would probably start out using the body model available from the

AnyBody Research Project.

This tutorial, being of introductory nature, will instead skip to a new subject: How can we add realistic

geometries of bones and other elements to our model?

Now, let's continue to Lesson 6: Adding real bone geometrics

Here's an AnyScript file to start on if you have not completed the previous lesson:

So far, the graphics of the model you have developed is what we can call a stick figure representation. This

is a straightforward way of seeing the model and it reflects the mechanics very vividly, but it does not look
