WESIG the natural logarithm <strong>of</strong> the geometric standard deviation <strong>of</strong> particle sizes in<br />

= wesig the assumed lognormal distribution <strong>of</strong> entrained debris during a given time ~<br />

stop. Default = in(2).<br />

EOI the keyword required <strong>for</strong> terminating the DHEAT, RPVCAV, and WEBER<br />

blocks.<br />

14.2.8 Timestep and Time Zone Input<br />

The TIMES block establishes the maximum system timestep size, the maximum edit timestep, and<br />

the total allowable CPU calculation time. The edit timestep by definition is the interval at which<br />

in<strong>for</strong>mation is written to the plot file. It is smaller than or equal to the interval at which long edits<br />

are written to the main output file. The TIMES block also defines the times at which restart data are<br />

written to the restart file.<br />

Cput the maximum CPU time limit. (s)<br />

tstart the problem start time. Note that the problem start time can be positive, zero,<br />

or negative. (s)<br />

The following set <strong>of</strong> three variables is repeated “ntzone” times, one set <strong>for</strong> each time zone:<br />

timinc the maximum system timestep size in the time zone. (s)<br />

edtdto the maximum edit timestep, or interval at which plot in<strong>for</strong>mation is written<br />

to the plot file(s). For the long and short edit frequency, see Section 14.2.8.1,<br />

Frequency <strong>of</strong> Print Output. Plot output can also be controlled more precisely<br />

using the PLAUTO options, see Section 14.2.9.3. (s)<br />

tstop the end time <strong>of</strong> the time zone. (s)<br />
