Hello, Thank you for sharing this video. I've encountered an issue while trying to use an expression in the "Cell zone conditions" section. Specifically, I'm attempting to specify a law governing the rotational velocity of a circular mesh portion. To achieve this, I've enabled the "Mesh motion" option and configured the "Expression" within the "Rotational velocity" tab. Now, I'm writing my expression in the "Expression editor" window. The problem I'm facing is that, despite specifying the unit as [deg/s] for the rotational velocity in my expression, the plotted curve (a function of time) is displayed in [rad/s]. I've attempted to change the selected unit in the "Set Units" window (under General -> Units...), switching it from [rad/s] to [deg/s], but it appears to have no effect on the plot displayed in the Expression editor. Could you please advise on how I can plot my expression in the desired unit? Many thanks anyway 😄
