No problem! Fix a location, apply a force and get a result in a second or two. Notice how the results display (the blue and colored stool on the right) is smooth and continuous and well covers the entire stool geometry.

Now let's say I want to simulate this stool sitting on top of the Millennium Falcon (stool not to scale):

What do my simulation results look like now?

If you look closer at the stool in this larger simulation, you will notice that it is not fully captured by the fidelity of the simulation:

Why does this happen? 

Discovery Live simulates an entire problem all at once. This means, the larger geometrically the problem you simulate, the less small detail you can resolve. This is what you can see with the example above.

Does Discovery Live let me turn up the fidelity?

Yes! Above the Play button you will find a "Fidelity" slider that let's you turn up the resolution:

What happens if I do that with our model above?

Now you can see that the stool has been better resolved.

The effect of GPU size on fidelity

It is important to note that because Discovery Live is designed to provide an interactive workflow for a wide range of supported graphics cards, it adjusts the available fidelity range (minimum and maximum) to keep a fine balance between performance and level of detail. This means that depending on the available graphics memory and computational resources, the limit on what Discovery Live is able to resolve geometrically changes.

What can I do to capture more detail if I have already turned up the fidelity?

• Get a larger graphics card (more memory and faster clock speed) - This will allow you to simulate larger problems with more detail.
  
• Simulate a smaller problem - Can you split the model into smaller regions and apply appropriate boundary conditions to those smaller regions?
