GRND

------ Real flag; value=-10110.0 ------

GRND....To set a quantity equal to GRND is an indication that the EARTH program is to look in the appropriate place in the open-source Fortran file GROUND.HTM information. For example, RHO1=GRND means that a sequence in GROUP 9 of GROUND is to be sought, in which coding has been provided for the setting of an array of values of first-phase density.

The user will have provided the appropriate coding in the just-shown template file, compiled the subroutine, and re-built the earth executable.

Coefficients and values in COVAL arguments can also be set to GRND, GRND1,....GRND10, for the provision of non-linear sources. Enter COVAL for more information.

GRND has the numerical value -10110.0 .


GRND1

----- Real flag; value=-10120.0 ------ groups 2,3,4,5,9,10,11 and 13.

GRND1....acts in the same way as GRND ( see GRND for details ), but permits GROUND to distinguish options according to value. For example, subroutine GXRHO distinguishes the following options ( amongst others ):

RHO1=GRND1 for an enthalpy-dependent density field; and
RHO1=GRND3 for an isentropic-gas-law density field.

See PHENC entry GRNDx.

GRNDx, ie GRND1, GRND2, .......... GRND10 and their equivalents.

Since the earliest days of PHOENICS, these variables have been used for making selections, in the Q1 file, of options in GROUND files.

Starting with version 2.2, SATELLITE recognises certain equivalents, the names of which indicate the meanings of the choices.

The following lists enumerate these. The equivalent names may be entered with either upper-or lower-case characters.

More such equivalents will be introduced for multi-phase flow and other problem classes

The following may be used for GRNDx:
