During an initialization of a simulation of the behavior of an industrial plant containing a number of components, a particularly reliable parameter input is intended to be ensured with a particularly low outlay. A coupling part, a pointer vane and at least one pointer section are arranged between the pointer and the axle. Reaction mixtures corresponding to these methods are also described. Each tubular head secures and suspends a tubular string in the well bore. A first and a second cylindrical protrusion are positioned proximate the bottom surface of the ice storage bucket.
