# block.zone.strain.rotation.inc

Syntax

## Tensor Access

t = block.zone.strain.inc(bzp<,i1<,i2>>)

Get the zone rotational increment tensor, based on the current displacement field.

Returns: t or f - zone rotational increment tensor, or, if the optional indices are supplied, the specified tensor value bzp - block zone pointer i1 - optional tensor index that, if used alone, ranges from 1 to 6 and returns the the $$xx$$, $$yy$$, $$zz$$, $$xy$$, $$xz$$, and $$yz$$ tensor values, respectively. i2 - option tensor index 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.

## Value Access

f = zone.strain.inc.xx(bzp)

Get the $$xx$$-value of the zone rotational increment based on the current displacement field.

Returns: f - $$xx$$-value of the zone rotational increment tensor bzp - block zone pointer
f = zone.strain.inc.xy(bzp)

Get the $$xy$$-value of the zone rotational increment based on the current displacement field.

Returns: f - $$xy$$-value of the zone rotational increment tensor bzp - block zone pointer
f = zone.strain.inc.xz(bzp)

Get the $$xz$$-value of the zone rotational increment based on the current displacement field.

Returns: f - $$xz$$-value of the zone rotational increment tensor bzp - block zone pointer
f = zone.strain.inc.yy(bzp)

Get the $$yy$$-value of the zone rotational increment based on the current displacement field.

Returns: f - $$yy$$-value of the zone rotational increment tensor bzp - block zone pointer
f = zone.strain.inc.yz(bzp)

Get the $$yz$$-value of the zone rotational increment based on the current displacement field.

Returns: f - $$yz$$-value of the zone rotational increment tensor bzp - block zone pointer
f = zone.strain.inc.zz(bzp)

Get the $$zz$$-value of the zone rotational increment based on the current displacement field.

Returns: f - $$zz$$-value of the zone rotational increment tensor bzp - block zone pointer
