RE: How to use "mass scaling" in this Example ?
For example, the following:
*FIXED MASS SCALING, TYPE=BELOW MIN, DT=1.0E-7
OR:
*VARIABLE MASS SCALING, TYPE=BELOW MIN, DT=2.0E-7, FREQUENCY=10

*fixed mass scaling and *variable mass scaling are not supported for eulerian elements.

You can only use mass scaling for lagrangian domains, not Eulerian. You ould try increasing the density of your Eulerian material though, which would have the same effect.

Bassmanjax got it though, and its that you cannot apply mass scaling to the Eulerian domain. Mass scaling will multiply the mass in an element, that changes very little mind you, to reach a certain value. In the Eulerian domain, the material doesn't move with a set of nodes, but through them, so the mass of an "element" of Eulerian material can be in incessant flux, so changing the mass of these elements would constantly be adding and subtracting material from the model.
