The tCur of a turn is calculated usng a node VDF and a turn VDF (Fundamentals: Node impedance of nodes VD function).
1. For the nodes desired, specify the Nodes VDF method for node impedance calculation (Selecting the method for node impedance calculation).
2. Make sure that the values of the following input attributes are correct at the selected nodes:
- Capacity PrT, t0 PrT and Type Number for turns (Managing turns)
- Capacity PrT and t0 PrT for nodes (Managing nodes)
- TModelSpecial (TModel receives penalty by node) = 1 for minor links towards the node (Managing links)
3. For each turn type used in the network, select the appropriate VDF (Selecting VDFs for turn types).
4. For each node type used in the network, select the appropriate VDF (Selecting VDFs for node types).
5. Calculate the node impedances with an appropriate method (Methods for node impedance calculation).
