Choice of amount of segment and charge information to be printed


This note concerns the amount of information to be displayed on the screen or put in the output data file. The amount of information is chosen by the user. The choices are 'nearlyzero/partial/most/all'.


There is a separate choice for the level of ray information.


'nearly zero': Only the most essential information is given, such as the stop messages.


'partial' information: The usual option.


'most': An option that is useful at the beginning of a study.


'all': Useful if you are a new user or if you are trying to identify an apparent error. This option gives all the notes and comments, and all the warnings that the program gives when it senses possible trouble. Another result of 'all' is that information on potentials and fields along the axis, if requested, is put in the output data file. Yet another reason for using 'all' is to obtain the individual charges on the segments, which are needed for capacitance calculations (but note that the charges are printed only the first time that they are calculated).


Headings of tabulated data are sometimes omitted with the options 'most' and 'partial', to aid in the subsequent editing or use of these data..


To omit all headings and text (while retaining the numbers) for segments and rays click on ‘no headers’ on the ‘segments and charges’ sheet. This puts nh (for 'no headings') in the first two spaces of the caption line -that is, the first line of the input data file.


To separate data by commas, which can be useful for processing data with an external program package, click on ‘separate by commas’ below the ‘no headers’ button. This puts nhc in the first three spaces of the caption line.

For users who are editing or constructing an 'input data file' without the use of the data-builder -that is, pre-processor:

But Manual editing is certainly not recommended -it is a relic from the time when the databuilder was not available All users are strongly encouraged to use the databuilder, which always gives the correct formats and which has many options for which the formats are not described or easily deduced.


The choices 'nearlyzero/partial/most/all' are denoted in the data file by the letters 'n/p/m/a' respectively.


To omit all headings and other words (while retaining the numbers) put nh (for 'no headings') in the first two spaces of the caption line -that is, the first line of the input data file.
