Comments
 The initial state for brick may be defined by more than one block.
 If
Nb_integr > 1, the optional continuation lines must be
repeated for each integration point, if Keyword2 =
STRS_FGLO and 8node solid element with 1 or 8
integration point.

 If
Nb_integr > 1, the optional continuation lines have to be
repeated for each integration point, if Keyword2 =
STRS_FGLO and 16 or 20 node solid elements, 8 node HA8
elements, 8 node HSEPH elements, 6 node PA6 elements; 10 nodes tetrahedron or
Pentahedron 6 nodes.

 nptr, npts and nptt are only useful in /PROP/TYPE22 (TSH_COMP).
 Using
/INIBRI/STRS_FGLO you are assuming there is no density of
the deformed elements. Before the first cycle Radioss will check consistency of the input stress tensor with material data
(stiffness and density).
(1) $$D=\frac{{s}_{11}+{s}_{22}+{s}_{33}}{3}Bulk\cdot \left(1\frac{\rho}{{\rho}_{0}}\right)=0$$Where, ${\rho}_{0}$
 Density defined in the Starter file
 $\rho $
 Density in the state file
If the stress is not fulfilled, then Radioss will correct the diagonal entry of the stress tensor:(2) $${s}_{ii}^{new}={s}_{ii}^{initial}D$$
