what does table mean in oscillatingFixedValue?
 
I' m new in OpenFOAM 2.10. Recently I finished the case "oscillatingBox" with the solver potentialFreeSurfaceFoam. The oscillating amplitude is given by a table, and I just don't know the mathematics expression that a table is present.

amplitude table
(
( 0 0)
( 10 0.025)
(1000 0.025)
);



Thank your for help.

Greetings T.Matrix and welcome to the forum!

If I remember correctly, this table is used for linear interpolation.
From 0 to 10 seconds, it rises linearly from 0 to 0.025; then from 10 to 1000, it stays at 0.025.

Best regards,
Bruno

Thank you, Bruno:

I analysis the oscillating amplitude with your advise. The first row is varying time, and the second row present the oscillating amplitude, and the table gives a message that oscillating amplitude is varying with time, is it right?

Best regards,
