# Flow Analysis

After completing all three inputs in the **Flow Analysis** block, the simulation will automatically run and produce your results.

## GPU Memory Considerations

Recall that Flow Analysis runs on GPU memory. Before running a full simulation, the **Flow Analysis** block estimates available GPU memory. If insufficient, you will see an insufficient memory error.

If your analysis runs slowly or encounters memory errors, you can free up available memory by:

* Decreasing your nTop resolution in the bottom-right corner of your screen
* Closing other nTop instances and GPU-intensive applications

## Monitor Block Progress

To monitor progress as your flow analysis runs, you can open the Log Panel.
