# Effect of Supercycling time interval

A part of the challenge is to study the effect of the supercycling interval on the overall solution time.

The simulation was run for time intervals of 0.05 s, 0.03 s, 0.02 s, and 0.01 s. However, the results obtained were inconclusive.

Attached is the files containing the solution time details.

What trend was to be expected?

@raj-dave - The main thing that you need to look at it how the solid temperature is getting affected. The expected output is a graph that shows the temperature of the solid region or at a monitor point. This plot should be made at different interval-timings and must be overlaid on a single figure. Let me know if this does not make sense.
