This commit adds conversion factors for the ECL LAB unit
conventions--notably Atmospheres for pressures, Hours for time,
Grams for mass, and cubic centimetres for volumes.
Every header is self-contained and includes only what it must to
function, relying on users include what they need in source files,
adopting a pay-what-you-use model (in particular for internal
dependencies).
This is required for keywords which do not use "every-day" temperature
values but thermodynamic ones or keywords that use "per degree"
values. Examples of such specimen are the OILCOMPR and WATDENT
keywords.
Also, I tried to convert all keywords that use reservoir volumes and
the associated code. Although I tried my best on that front, it might
not be enough. (in any case, I consider it very unlikely that there
are any regressions caused by this.)
this is required because Eclipse is inconsistent when specifying
transmissiblities: the only difference between transmissibilities in
metric and field units is that the pressures are in bars instead of
PSI, i.e. the numerator for metric units is still given in centi-Poise
times bbl. This makes it impossible to specify the transmissibilities
in terms of their constituting bits...
this is just the result of
```
find -iname "*.[ch]pp" | xargs sed -i "s/ *$//"
find opm/parser/share/keywords -type f | xargs sed -i "s/ *$//"
```
so if it causes conflicts with other patches, the others should get
priority. The rationale behind this patch is that some people tell
their editor to remove white space which leads to larger than
necessary patches...
this requires the possibility of specifying an offset for the SI
conversion because Eclipse in its eternal wisdom chooses to specify
temperatures using degrees Celsius and degrees Fahrenheit instead of
using Kelvin an Rankine...
this is meant for those nasty keywords where the dimension of an entry
depends on a user-defined value of some field of a (potentially
different) keyword. One example for this are the surface rates of the
produced fluids for the .CON(INJ|PROD).* keywords which exhibit
different units depending on whether the user choses to control for
the surface gas or the liquid rate.
the approach taken in this patch is to convert all numbers to NaN if
the unit is queried in SI (via item->getSIDouble()). It might be more
desireable to throw an exception in this case, but this approach would
be more elaborate and NaNs should be quickly noticeable by the users
of this code.
I tried to adapt all implemented keywords, but it's quite likely that
I missed some...
the motivation for this is the 'TSTEP' eclipse keyword.
the reason why this dimension is not simply called 'Time' is that in
eclipse, different keywords might use different units, e.g. one
keyword could use seconds, another could use years while a third uses
days. As an added bonus, the used time units may be different for
different scales but identical in others (e.g., for one keyword times
might be specified in 'days' for the metric as well as for the
labscale, but in 'days' and 'hours' for another second keyword.)
