The thermal bowing option in PCL-Gold (FEPipe beam element pipe stress program) allows bowing input on an element by element basis and an orientation vector but only one set of bowing data per run/model.

PCL-Gold allows different bowing data anywhere in the model and no bowing (off). You CANNOT have have multiple bowing cases on each element analogous to multiple thermal cases.
