Shape <iv> = 2 (bar), #nodes = 2

• <config> 0, 1, 2 become a beam element
• <config> 5 becomes extra nodes on rigid parts
• <config> 7 becomes a lumped mass
• <config> 8 becomes a spherical joint
• <config> 30 becomes a seatbelt element
• <config> 31 becomes a retractor
• <config> 32 becomes a slipring

  The following configurations becomes springs/dampers, grounded if <n1> = <n2>:

• <config> 6, 10 becomes a translational spring
• <config> 11 becomes a rotational spring
• <config> 20 becomes a translational damper
• <config> 21 becomes a rotational damper

Shape <iv> = 2 (bar), #nodes > 2

• If #nodes = 4 become revolute joints
• If #nodes = 6 become translational joints.

Shape <iv> = 3 (tria):

• <config> 0, 3 become 3 noded shells (n3 = n4)

Shape <iv> = 4 (quad):

• <config> 0, 3 become 4 noded shells

Shape <iv> = 5 (tetra):

• <config> = 0, 4 become 4 noded solid tetrahedra (n4=n5=n6=n7=n8)

Shape <iv> = 7 (wedge):

• <config> = 0, 4 become 6 noded solid wedges (n5=n6, n7=n8)
• <config> = 1 become 6 noded thick shells (n3=n4, n7=n8)

Shape <iv> = 8 (hex):

• <config> = 0, 4 become 8 noded solid hexahedra
• <config> = 1 become 8 noded thick shells

All other element types are ignored.
