Minimum Distance |

You may optionally specify a Minimum Distance input for a Clear timetrace analysis. This is a separation value below which you want Clear to consider that interference has occurred when counting the number of times the two structures interfere. This defaults to a value of zero, in which case interference is deemed to occur only when the two structures are actually predicted by Clear as being in contact. The rationale for this entry is as follows. Clear calculates the separation or clearance between structures at discrete times. If two structures do indeed come intermittently into contact, the likelihood of this occurring at a Clear solution time is small. For this reason you specify the Minimum Distance value. The assumption is that if the distance between the two structures at a particular solution time is less than this minimum, then it is likely that they do come into contact between Clear solution times. In this case the program should increment its running total of contacts or interferences, and if possible calculate impact velocities and accelerations.
•*ANALYSIS TYPE is used to specify the Clear analysis type and related parameters, including the Minimum Distance input.
