block zone initialize command

Syntax

block zone initialize keyword <range>

Primary keywords:

extra    state    stress    stress-principal    stress-xx    stress-xy    stress-xz    stress-yy    stress-yz    stress-zz

Initialize zone variables.

extra i a[zoneinitializeoptions]

extra variable for array index i

state i

The plasticity indicators for tetrahedrons are set to i . Normally the value of i used is 0 in order to reset the failure indicators.

stress <keyword ...>

Initialize the full stress state, specified by component. A component that is not specified is assumed to be zero.

WARNING - this command only initializes zone stress. To initialize both zone and contact stress use block insitu.

xx f

xx-component of stress

xy f

xy-component of stress

xz f

xz-component of stress

yy f

yy-component of stress

yz f

yz-component of stress

zz f

zz-component of stress

stress-principal <keyword ...>

Principal stress states, specified by value and by direction using the available keywords. Note that at least two directions must be specified, and magnitudes not specified are assumed to be zero. Note that the [zoneinitializeoptions] is available after each of the following keywords, allowing them to be varied in space independently.

WARNING - this command only initializes zone stress. To initialize both zone and contact stress use block insitu.

direction-intermediate v [zoneinitializeoptions]

Direction of intermediate principal stress.

direction-maximum v [zoneinitializeoptions]

Direction of maximum principal stress.

direction-minimum v [zoneinitializeoptions]

Direction of minimum principal stress.

intermediate f [zoneinitializeoptions]

Intermediate principal stress magnitude.

maximum f [zoneinitializeoptions]

Maximum (most postitive) principal stress.

minimum f [zoneinitializeoptions]

Minimum (most negative) principal stress.

stress-xx f [zoneinitializeoptions]

Initialize zone \(xx\)-stress (total).

stress-xy f [zoneinitializeoptions]

Initialize zone \(xy\)-stress (total).

stress-xz f [zoneinitializeoptions]

Initialize zone \(xz\)-stress (total)

stress-yy f [zoneinitializeoptions]

Initialize zone \(yy\)-stress (total)

stress-yz f [zoneinitializeoptions]

Initialize zone \(yz\)-stress (total)

stress-zz f [zoneinitializeoptions]

Initialize zone \(zz\)-stress (total)

block zone initialize Keyword Block

The following keywords may be used to modify a supplied value. If the description of the modifier keyword mentions what type of value it may be applied to (e.g., scalar value, vector value, etc.), be sure there is a match between the modifier and the main keyword value.

The keywords below are applicable to each of the following keywords of the block zone initialize command: extra, stress-xx, stress-xy, stress-xz, stress-yy, stress-yz and stress-zz. direction-intermediate, direction-maximum, direction-minimum, intermediate, maximum and minimum.

add f

Add the specified value to the existing value.

gradient v <origin v >

Apply a gradient to the scalar-value provided.

multiply f

Multiply the existing value by the specified value.

vary v

Apply a linear variation to the scalar-value provided.
