Comments
- Moving skew defines a local coordinate system, defined by three nodes. At each time, the actual orientation of the skew is recalculated according to the actual position of these nodes.
- For moving skews, the skew system is moving and is defined by node identifiers
node_ID1, node_ID2 and node_ID3.The axis definition depends on the input for Dir.
- When Dir=X
node_ID1 amd node_ID2 define
node_ID1 and node_ID3 define - When Dir=Y
node_ID1 and node_ID2 define
node_ID1 and node_ID3 define - Case Dir=Z
node_ID1 and node_ID2 define
node_ID1 and node_ID3 defineThe skew is defined by , and
- When Dir=X
- When defining some conditions with respect to the skew in cylindrical coordinate system, the axis of the cylindrical coordinate system is assumed to pass through node N1.
