/INISHE/ORTH_LOC or /INISH3/ORTH_LOC

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

/INISHE/ORTH_LOC/`unit_ID` or /INISH3/ORTH_LOC/`unit_ID`

For each layer (integration point); except for SH_ORTH property (only one Format):

$ϕ_{i}$		$α_{i}$

Field	Contents	SI Unit Example
`unit_ID`	Unit Identifier. (Integer, maximum 10 digits)
`shell_ID`	Element identifier. (Integer)
`nb_lay`	Number of layers. Must be equal to the number of layers given in the shell property, except for /PROP/SH_ORTH (in this case `nb_lay` = 1). (Integer)
`npg`	Number of surface quadrature points. (Integer)
`ndir`	Number of orthotropy direction for each layer. (Integer)
`Iunit`	Input angle unit flag. = 0 Angle in radian = 1 Angle in degree (Integer)
$ϕ_{i}$	Angle of first direction of orthotropy relatively of first direction of the local reference frame. (Real)	$[rad]$ or $[\deg]$ if `Iunit` =1
$α_{i}$	Angle of second direction of orthotropy for layer i, relatively of first direction of orthotropy. Only used for properties /PROP/TYPE16 (SH_FABR) and /PROP/TYPE51. (Real)	$[rad]$ or $[\deg]$ if `Iunit` =1

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.
Local reference frame is described in Local Reference Frame of the Radioss Theory Manual.
This option is compatible only with the orthotropic shell property, like /PROP/TYPE9 (SH_ORTH), /PROP/TYPE10 (SH_COMP), /PROP/TYPE11 (SH_SANDW), /PROP/TYPE16 (SH_FABR) and /PROP/TYPE51.
