rblock.moi.real — PFC 6.0 documentation

t = rblock.moi.real(b<,i1<,i2>>)

rblock.moi.real(b<,i1<,i2>>) = t

Get/set the rigid block real moment of inertia.

Note

In 2D, the polar moment of inertia is used so the optional integers are not available and a float is returned.
When modified, no other rigid block attributes are changed (e.g., pebble sizes, rigid block volume). 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 rigid block unless the user changes the fix state (see rblock.moi.fix).

Returns:

Returns:	t - rigid block real moment of inertia tensor or value
Accepts:	t - rigid block real moment of inertia tensor or value
Arguments:	b - rigid block pointer i1 - Optional tensor index that, if given without i2, ranges from 1 to 7, accessing the xx, yy, zz, xy, xz, and yz tensor values. i2 - Optional tensor notation that must be given with i1. In this case, i1 corresponds to the first index of the tensor position and i2 to the second in the row/column format. For instance, i1 = 1 and i2 = 3 returns the xz tensor value.

t - rigid block real moment of inertia tensor or value

Accepts:

i1 - Optional tensor index that, if given without i2, ranges from 1 to 7, accessing the xx, yy, zz, xy, xz, and yz tensor values.

i2 - Optional tensor notation that must be given with i1. In this case, i1 corresponds to the first index of the tensor position and i2 to the second in the row/column format. For instance, i1 = 1 and i2 = 3 returns the xz tensor value.
