Hi Annika,

The 'orientation' seems indeed to be left out from the 'connector'
output. But I think you can use the 'extra' parameter instead. So
the following

orientation = {
    'name': 'radial2',
    'definition': 'coordinates',
    'system': 'cylindrical',
    'a': (0.0, 0.0, 0.0),
    'b': (0.0, 0.0, 1.0),
    'extra': '3, 90.0',
}
connector = {
    'name': 'connector',
    'sectiontype': 'UJOINT',
    'extra' : 'radial2',
}

would come out in the .inp file as

*ORIENTATION, NAME=RADIAL2, DEFINITION=COORDINATES, SYSTEM=CYLINDRICAL
0.0, 0.0, 0.0, 0.0, 0.0, 1.0
3, 90.0
*CONNECTOR SECTION, ELSET=connector_set
UJOINT
radial2

Hi!

I want to add planar connectors to my stent model in abaqus. I generated the geometry and meshing with pyformex. I was able to add join connectors. But I´m having troubles with planar connectors since they need an orientation definition and somehow the keyword deifintion is not added to the abaqus input file.
Does someone know how to define the properties and add them to the PropertyDB in order to obtain all required arguments in the input file?
That´s how I got the element section:

PDO = {
'name': 'PDO',
'young_modulus': E[i],
'poisson_ratio': v,
'density': dens,
}
filament = {
'name': 'filament',
'sectiontype': 'CIRC',
'radius': dF[i],
'material': 'PDO',
}
wiresection = ElemSection(section=filament, material=PDO)
P=PropertyDB()
P.elemProp(prop=1, section=wiresection, eltype='B31')

Now I am wondering how to define the connectorsetion.

connector = {
'name': 'connector',
'sectiontype': 'planar',
'orientation' : ??,
}
?
orientation = {
'name': 'orientation',
'system' : 'rectangular',
'definition' : ??,
}
?
connectorsection=ElemSection(section=connector, orientation =??)
P.elemProp(prop=2, section=connectorsection ,eltype='CONN3D2', orientation=orientation)

Thank you,
Annika
