Set the rblock principal moments of inertia from an array. When modified no other rblock attributes are changed (e.g., pebble sizes, rblock volume, etc.). The specification of the moment of inertia in this way results in the principal moments of inertia being in a fixed state so that they will not be automatically updated when scaling a rblock unless the user changes the fix state.

Set the rblock applied moment from an array.

Set the rblock velocity from an array.

itasca.rblockarray.set_vol(data: array float{rblock}) → None.

Set the rblock volume from an array. In 2D this is the volume per unit thickness. When modified no other rblock attributes are changed (e.g., moment of inertia, pebble sizes, etc.). The specification of the volume in this way results in the principal moments of inertia being in a fixed state so that they will not be automatically updated when scaling a rblock unless the user changes the fix state.
