Hello everyone

Recently, I ran a transient cavity flow simulation and I post-processed it in CFD-Post. I probed the data by creating a point inside the cavity

The time history pressure plot was okay, but when I want to use the Fast Fourier Transform feature (with Hanning window), there was an error message after "loading", "Internal Error: Curve is Empty".

Did I do something wrong?

I had the same problem with a time-dependent fluctuation chart. It seems that CFD Post can only process time-series taken at equal time steps in a continuous (consecutive) manner.

Hope it helps
