'enq' <set> <set> ['set' <setname> ]| -> ['rec' <x-value>|'_' <y-value>|'_' <z-value>|'_' ]| -> ['cyl' 'x'|'y'|'z' <r-value>|'_' <axis-value>|'_' ] -> <tol> 'i'|'a'|'h'|'l' [<value>]This command is used to locate entities from a certain set (first provided set) and stores them in the second set. The following entities are handled: nodes, points, lines, surfaces. But surfaces can only be identified if the command ``rep
>'' was issued before. In case of nodes with related values (results) it will also determine the highes or lowest value in the specified range, or, all nodes above or below a certain value. The coordinates might be taken from one node or point in a given 3rd set or given in cartesian coordinates (option rec) or cylindrical coordinates (option cyl). Some coordinates might be omitted to specify an infinite range. The '_' key has to be used in this case. The mode is defined by the keys 'i' individual, 'a' all, 'h' high, 'l' low, were h and l will search the highest or lowest value in range. This value will also be written to a file for automatic processing purposes. For example
In combination with a certain value
enq all newset rec 10. _ 100. 0.1 h 1013.
all nodes with a value above ``1013.'' would be stored in set ``newset''. The command
enq domain1 newset cyl x 100. 10. 0.1 a
will search for entities in set 'domain1' at radius:100. around x at x:10. with a tolerance of 0.1. All entities in range are stored in set 'newset'.
The following example illustrates the use of ``enq'' to find the highest value close to a location given by a node-number:
# activate dataset 3 with entity 7: ds 3 e 7 # read a file with one node to define a set: read pos1.frd pos1 # search the highest value around a radius of 1: enq all t set pos1 1. h # move the file with the search result to a meaningfull name: sys mv enq_lc3_e7_1.out pos1.out
