- the timeSelector is often used to select single or multiple times
(eg, for post-processing). However, there are a few applications
where only a *single* time should be selected and set.
These are now covered by this type of use:
timeSelector::addOptions_singleTime(); // Single-time options
...
// Allow override of time from specified time options, or no-op
timeSelector::setTimeIfPresent(runTime, args);
In some cases, if can be desirable to force starting from the
initial Time=0 when no time options have been specified:
// Set time from specified time options, or force start from Time=0
timeSelector::setTimeIfPresent(runTime, args, true);
These changes make a number of includes redundant:
* addTimeOptions.H
* checkConstantOption.H
* checkTimeOption.H
* checkTimeOptions.H
* checkTimeOptionsNoConstant.H
ENH: add time handling to setFields, setAlphaField (#3143)
Co-authored-by: Johan Roenby <>
STYLE: replace instant("constant") with instant(0, "constant")
- avoids relying on atof parse behaviour returning zero
