To control a bandwidth without the need for a large-capacity buffer. In one embodiment, a source code file is translated to obtain a translation error list. With this arrangement, even if contact candidate particle pair data updating is decimated and part of contact determination is accordingly omitted to increase a computing speed of the contact determination, accuracy of simulation will not be reduced. Upon completing the preparation, the finishing device notifies preparation completion information to the image processing apparatus. The temperature of the ambient air of the detector housing is set by a control system that uses the temperature of the detector system as controlled variable. In the inventive filling machine a recess is arranged in an upper surface of the volume such that the valve body is at least partly insertable in the recess in the rest position.
