# Unable to view Live results from Topology Optimization

## Issue:

I am not able to see the Live results from **Topology Optimization**.

## Applies to:

* Topology Optimization

## Cause:

If the **Topology Optimization** block is a list, then you won't be able to see the live results. To determine if a block is a list, look for the 3 horizontal bars icon on top of the block icon.

Look upstream in your workflow for Topology Optimization inputs that shouldn't be a list like the Simulation Model or FE Solid Model. Please refer to our [How to work with lists](/help-articles/knowledge-base/user-interface/how-to-work-with-lists) article to better understand how lists function in nTop.
