1. Caesar II won't calculate the SIF for a cross. You can trick the program by offsetting the branches so that they come in at two different node numbers, spaced very close together. But 2. Caesar II won't consider the 2D rule as you stated.
Otherwise, if you have a different way to calculate the SIF for the cross then you can enter them into Caesar II, once for each element, all on the intersection node. Leave the TYPE field blank if you do this.
