The invention relates to a method for simulating an impact of particles/radiation on an object: (a) Providing a control memory including control memory locations and a mass memory including mass memory locations. (b) Building a simulated particle/radiation unit, wherein this particle or the radiation unit is designated for impact on the object. (c) Defining at least one property/energetic state of a particular, individual particle/radiation unit. (d) Carrying out a simulated impact of the particular individual particle/radiation unit on the object, wherein a distribution function of an impact site and/or of a velocity of the particular individual particle/radiation unit is used. (e) Determining or querying at least one local property and/or a local energetic state of at least one affected object element. (f) Determining or querying a collision event caused by the impact and acting on the individual particle/radiation unit and/or the affected object element or volume element. (g) Determining a consequence of the collision event at least on the affected volume element or object element. (h) Storing a newly determined or an unchanged control data value in the corresponding control memory location and a newly determined or unchanged mass data value in the corresponding mass memory location.

The invention relates to a water-based biodegradable and non-toxic functional fluid for mechanical drives, preferably for use in steam engines. The object of providing such functional fluids for use in mechanical drives, particularly for the hydrodynamic lubrication of plain bearings, preferably for crankshafts of superheated steam engines, having customary bearing play which is not overly precise, is achieved. It should be capable of being used in closed power plant systems also at sump temperatures higher than 120&#xb0; C., e.g. in the crankcase under a crank shaft, and should be water-based or water-dilutable. According to the invention, this is achieved by addition of a low percentage of polyaspartic acid to water or to water/glycol mixtures, preferably polyaspartic acid having a molar mass of from greater than 1 000 to 10 000 g/mol being used.
