In the OSWEC tutorial documentation, the moment of inertia is written as

I would think that this moment of inertia should be about the y axis given that the y axis is the pitch axis in WEC-Sim.
In addition, in the tutorial wecSimInput File, the moment of inertia is written as
body(1).inertia = [1.85e6 1.85e6 1.85e6]; % Moment of Inertia [kg-m^2]
with all three of the directions as equal.

Is this intentional, or is this a typo in both places as it seems to be?

Also, has there been a change in the notation of moment of inertia of a body in the code? I have been using my downloaded version (and downloaded tutorial input file) with body(i).momOfInertia, but the documentation I am looking at now simply uses body(i).inertia.

Personal project context
I am trying to model a similar OSWEC and thought that the tutorial could be a good point of reference.
