# zone.strain.rate

Syntax

t := zone.strain.rate(z)

Get the zone strain rate, based on the current velocity field.

Returns:

t - zone strain rate tensor or value

Arguments:

z - zone pointer

Component Access

f := zone.strain.rate (z)->xx

f := zone.strain.rate.xx(z)

Get the $$xx$$-component of the zone strain rate, based on the current velocity field.

Returns:

f - $$xx$$-component of the tensor

Arguments:

z - zone pointer

Access other tensor components ($$yy$$, $$zz$$, $$xy$$, $$xz$$, $$yz$$) by substituting the component name where $$xx$$ appears above. See Member Access Operator for information about accessing members from data types using ->.

Deprecated Component Access

Component access by adding an optional integer in the function arguments (zone.strain.rate(z,<int, <int>>)) is deprecated. It remains available but will not be supported in future versions. See Component Access with Integers in FISH on the Deprecated Commands and FISH page for details.

This is hidden. Added to include remaining vector component access functions for inline help.

f := zone.strain.rate.yy(p)
f := zone.strain.rate.zz(p)
f := zone.strain.rate.xy(p)
f := zone.strain.rate.xz(p)
f := zone.strain.rate.yz(p)
