/INISHE/ORTHO or /INISH3/ORTHO

Block Format Keyword Describes the initialization of orthotropy direction for shells element per element.

Format

If prop_type ≠ 9 (/PROP/SH_ORTH), read for each layer (nb_integr):

(1)	(2)	(3)	(4)	(5)	(6)	(7)	(8)	(9)	(10)
$ϕ_{1}$		$ϕ_{2}$

If prop_type = 9 (/PROP/SH_ORTH), read only one time 5:

(1)	(2)	(3)	(4)	(5)	(6)	(7)	(8)	(9)	(10)
$ϕ_{1}$		$ϕ_{2}$

Field	Contents	SI Unit Example
`unit_ID`	Unit Identifier (Integer, maximum 10 digits)
`shell_ID`	Element identifier (Integer)
`nb_integr`	Integration point number through the thickness Must be equal to the number of integration points given in the shell property. (Integer)
`prop_type`	Property element type (Integer)
`Vx`	X component of the reference vector (Real)
`Vy`	Y component of the reference vector (Real)
`Vz`	Z component of the reference vector (Real)
$ϕ_{1}$	Angle for first axis of orthotropy (Real)	$[\deg]$
$ϕ_{2}$	Angle between first and second axis of anisothropy (for property /PROP/TYPE16 (SH_FABR) only) (Real)	$[\deg]$

This option can be used to initialize the orthotropy direction for shells element per element. By default, property defined characteristics are used, those defined using this option are priority.
The projection of the reference vector on the shell surface defines a reference direction for orthotropy axis.
For each layer (integration point), the first orthotropy axis is defined at a given angle from the reference direction.
This option is compatible only with the orthotropic shell property like /PROP/TYPE9 (SH_ORTH), /PROP/TYPE10 (SH_COMP), /PROP/TYPE11 (SH_SANDW) and /PROP/TYPE16 (SH_FABR).
For Element of property /PROP/SH_ORTH (/PROP/TYPE9), only one orthotropy direction has to be defined.
