You can calculate the current impedances for all nodes or main nodes. The general and specific settings at the nodes determine how the impedances will be calculated (Calculating node impedances).
1. On the toolbar, click the 
Open 'Procedure sequence' window button.
The Procedure sequence window opens.
2. In the desired position of the procedure sequence, insert the Update impedances at node procedure of the Assignments category (Setting up and starting the procedure sequence).
3. Start the procedure (Executing procedures in the procedure sequence).
The impedances of the nodes and main nodes are updated.
