# Issue:

Why does my Topology Optimization Result get rid of important areas on my design?

Why is too much material removed when I run a Topology Optimization?

# Applies to:

- Topology Optimization

# Cause:

This can happen in areas of the model where you have Displacement Restraints, but no Forces. The algorithm running the topology optimization sees these areas as non-performing material, therefore removing the material.

# Solution:

Try these options to edit your Topology Optimization Result:

- Take another look at the Boundary Conditions in your model and edit them if needed
- Set up a Passive Region Constraint for the area that was removed
- If using a Volume Fraction Constraint, edit the value so less material is removed
