For a limit stop, when a connected node is present, the direction can also be specified. This is especially useful when the connected node is coincident with the limit stop node.

The limit stop direction must be specified when there is no connected node or there is a coincident connected node. If there is a non-coincident connected node and the direction is also specified, that direction will be used, otherwise the direction is calculated from connected node to the limit stop node.

In previous versions, when a connected node was present, the limit stop direction was calculated from the limit stop node to the connected node. This required the specification of limits in a "non intuitive" way.

Similarly for a skewed restraint, when a connected node is present, the direction can be specified which is especially useful when the connected node is coincident with the skewed restraint node.

Bug correction: Skewed restraint loads were not properly calculated when connected node was specified.

Bug correction: For Swedish and Norwegian codes, the pressure component of stress (i.e. pd/4t) used nominal wall thickness rather than usable wall thickness which subtracts corrosion allowance and mill tolerance from nominal thickness.
