This window lets you assign initial conditions from an Initial Condition Set to the selected element Group.
Check this box to fill the Group using an Initial Condition Set.
The advantage of filling using an Initial Condition Set is that if you later change one or more parameters in the set, you do not have to refill.
Use the pull-down menu to select the Initial Condition Set you want to use.
You can define new Initial Condition Sets by clicking the Init.Cond. button on the Navigation Bar or by clicking next to the option in this window.
