# I ran a simulation but my results don't show up as expected

## Issue:

I ran a simulation, but my results for the Von Mises stress don't register on the part, it shows solid purple. Changing the Boundary Conditions gives me the same result.

## Cause:

This can occur due to the upper bounds of the Stress HUD being too high for the stress experienced by the part.

## Solution:

Edit the values in the HUD to show the results on your part.
