ModalForce

Class ModalForce()

ModalForce(parent='MODEL', name='ModalForce_n', label='ModalForce_n', 
active=True, b1=None, b2=None, load_selected=0, usr_type='SCALE', user=False)

A disturbed force on a flexible body that exists in the modal form in the flexible body H3D.

Keyword Arguments

Argument	Data Type	Description	Default
name	String	The variable name.	ModalForce_n, for next available integer n.
label	String	The descriptive label.	ModalForce_n, for next available integer n.
parent	Object	The parent.	MODEL
active	Boolean	Used to activate or deactivate this entity.	True
b1	Body	The flex body the distributed force is to be applied.	None
b2	Body	The rigid body on which the reaction force acts on, when type is action reaction. Applicable only for ADAMS solvermode.	None
itype	Enum	The type of ModalForce. One of ACTION or REACTION. REACTION type of force is applicable only when solvermode is ADAMS.	ACTION
load_selected	Int	The selected load case as available in the flexible body H3D.	0
usr_type	Enum	One of SCALE or FORCE. Applicable when using user defined properties.	SCALE
user	Bool	Use user defined properties, if true.	False
usr_sub	Function	The expression passed to the user dll. When using solver expressions, Templex syntax (within ``) is used and all variables are enclosed in braces {} and the rest is treated as literal.	'USER()'
local_funcname	String	The function/subroutine name.	'MOTSUB'
use_local_dll	Bool	Uses a local function instead of default if True.	False
local_dll	File	The path of the local dll which has the local_funcname.	''
local_func_type	Enum	The type of the user subroutine. one of DLL, PYTHON or MATLAB.	'DLL'

Instances

scale (Nonlinear) : The scale applied for the force. Defaults to :.

Readonly Properties

loadlist (Any) : The list contains the load case id as available in the flexible body H3D. Load case ID generally matches with the ID specified in the finite element deck (.fem in case of OptiStruct) that was used to generate the flexible body. Defaults to None.

Examples

Create and modify attributes of a ModalForce.

   >>> # Import mview module
   >>> from hw import mview
   >>> mf = mview.ModalForce()
   >>> m.itype
   'ACTION'
   >>> bf1 = mview.Body(name="bflex_1, "useflex=True)
   >>> bf1.flex.MotionSolve.graphic_file = r"C:/Altair/mv_hv_hg/mbd_modeling/flexbodies/modalforce/gra_forecanard.h3d"
   >>> mf.b1 = bf1
   >>> mf.b1.name
   'bflex_1'
