To specify the Clear analysis type and related parameters.
Refer to Analysis Type for further information on this feature.
Two lines of data, defining the analysis type, and data specific to that type of analysis.
Line defining the analysis type:
TYPE=Analysis Type
Analysis Type can either be SNAPSHOT, TIMETRACE, or STATISTICS.
The format of the next line depends on the type specified, as follows.
Line for specifying SNAPSHOT data:
Time, No. of Points
Line for specifying TIMETRACE data:
Start Time, Minimum Distance, No. of Points
Line for specifying STATISTICS data:
Start Time, No. of Points
To specify data relating to a Clear snapshot analysis
Input: |
Description |
Time: |
The time at which the clearance snapshot is required. This defaults to the first database output time. |
No. Of Points: |
The number of points or locations on each element to be used in calculating clearances. This defaults to a value of 2. See Note (a). |
Notes
(a)The No. of Points entry must be an integer greater than or equal to 2. The default value of 2 means interference calculations are performed for the ends of the elements only. If more than 2 points are specified, interior points are distributed equally over each element.
To specify data relating to a Clear timetrace analysis
Input: |
Description |
Start Time: |
The time at which to begin calculating the time history of clearance. See Notes (a) and (b). |
Minimum Distance |
A separation value below which Clear is to consider that interference has taken place between the two structures. This defaults to zero, in which case two structures interfere only when they are actually predicted by Clear as being in contact. See Note (c). |
No. Of Points: |
The number of points or locations on each element to be used in calculating clearances. This defaults to a value of 2. See Note (d). |
(a)Use the Start Time entry to exclude initial transients from the clearance timetrace.
(b)The default Start Time used by Clear depends on whether the program is reading from one or two database files. If one database is being read, the default Start Time is the first database output time. If two databases are being read, Start Time defaults to the larger of the two database output start times. Of course if the two files have the same first database output time, this becomes the default.
(c)For a discussion of the significance of the Minimum Distance entry, refer to Minimum Distance.
(d)The No. of Points entry must be an integer greater than or equal to 2. The default value of 2 means interference calculations are performed for the ends of the elements only. If more than 2 points are specified, interior points are distributed equally over each element.
To specify data relating to a Clear statistics analysis
Input: |
Description |
Start Time: |
The time at which to begin calculating the time history of clearance. See Notes (a) and (b). |
No. Of Points: |
The number of points or locations on each element to be used in calculating clearances. This defaults to a value of 2. See Note (c). |
