I don't understand what is X-cor and height in the real ground of MMANA.
Can someone help me ?

I have wondered the same things. It appears to me that "radial boundary (R-cor)" probably specifies a round top-surface ground area and that "linear boundary (x-cor) probably specifies a rectangular top-surface ground area. I suspect that "Heig(m)" actually should be "Depth(m)" and that it is used together with a radial boundary or a linear boundary to specify ground volume.

However, these are only guesses. Someone else may have more definitive information.

I think you are right. That's also the way it looks to me.
