Assuming 2 load steps (load and lock):

pret = ExtAPI.DataModel.Project.Model.Analyses[0].AddBoltPretension()

pret.SetDefineBy(1, BoltLoadDefineBy.Load) # Step 1: Load

pret.SetDefineBy(2, BoltLoadDefineBy.Lock) # Step 2: Lock

pret.Preload.Output.SetDiscreteValue(0, Quantity(10, "N")) # Step 1: apply preload
