  • nodeprop –

    Nodal property

    (Default value = None)

  • maxseg –

    Meshed with elements that span at most maxsegdeg degrees per element

    (Default value = None)

  • propname –

    Boundary property ’propname’

    (Default value = None)

  • hide –

    0 = not hidden in post-processor, 1 == hidden in post processor

    (Default value = False)

  • group –

    the group the Arc1 object belongs

    (Default value = None)

  • is_draw (bool) – 1 to draw the list of surfaces given

Return type:

None

intersect_line(Z1, Z2)

Return a list (0, 1 or 2 complex) of coordinates of the intersection of the arc with a line defined by two complex

Parameters:

self (Arc) – An Arc object

Returns:

Z_list – Complex coordinates of the intersection (if any)

Return type:

list

is_on_line(Z)

Check is a point defined by its complex coordinate is on the arc

Parameters:

  • self (Arc) – An Arc object

split_line(Z1, Z2, is_join=False, prop_dict_join=None)

Cut the Arc according to a line defined by two complex “Above” is in the coordinate system with Z1 in 0 and Z2 on the X>0 axis

Parameters:
