Definition

Field Contents SI Unit Example
unit_ID Unit Identifier

(Integer, maximum 10 digits)

brick_ID Element identifier

(Integer)

nptr Number of integration points in direction r

(Integer)

npts Number of integration points in direction s

(Integer)

nptt Number of integration points in direction t

(Integer)

nlay Number of layers. 1

(Integer)

Alpha_lkji Yield stress scale factor of integration point lkji with:
l
Layer
k
in direction t
j
in direction s
i
in direction r

(Real)

Example

In this example use:

/PROP/SOLID Isolid=16 with Inpts=322 => must set nptr=3; npts=2; nptt=2 (then i=3; j=2; k=2 in Alpha_lkji).
Then the yield stress scale factor Alpha_lkji is below, and are totally $3×2×2=12$ Alpha_lkji values.
