In a prestress modal analysis, where the pre stress is given by a static analysis, how can we set the prestress environment to None (or to a static analysis)?

    One way is a shown below (2 systems exist A is a static system, providing the pre stress to a B Modal system).

    model = ExtAPI.DataModel.Project.Model
st=model.Analyses[0]
mo=model.Analyses[1]
prst=mo.InitialConditions[0]
prst.PreStressICEnvironment=st # Set st to None if no prestress is needed
