Time-Averaging

cyln · February 14, 2017, 23:14

Hello,

I have run a transient simulation in CFX and I would like to time-average it.

1) In the first step, I want to check when my simulation reaches statistically steady state.

2) In the second step, lets say my simulation reaches statistically steady state after 2000 time steps, I want to time-average my simulation.

It is first time I am doing this and I will appreciate any help.

Regards.

When you setup the analysis in CFX Pre there is a Tab in the results option (basically where you setup monitors, backup points etc) which allows you to perform time averaging.
