Units for simulation |
Usage |
Units NUM=ival where ival is the data structure number |
Description |
Overview The Units data structure is optional and allows definition of the units used for the simulation. If the units are specified they are also used to convert some parameters to the correct units. These operations comprise: •Automatic conversion of gravity loading if MPa and m specified. In this case density can be specified in Kg and m units.
|
 | Length Units for length |
Usage |
||||
|
||||
Description |
||||
Defines the units for length. Valid tags are: • "mm" - millimeters • "m" - Metres • "km" - Kilometres • "in" - Inches • "ft" - Feet
|
| Stress Units for stress |
Usage |
||||
|
||||
Description |
||||
Defines the units for stress. Valid tags are: • "MPa" - Mega Pascal • "kPa" - Kilo Pascal • "Pa" - Pascal • "Bar" - Bar • "psi" - Pounds/square inch
|
| Time Units for time |
Usage |
||||
|
||||
Description |
||||
Defines the units for time. Valid tags are: • "ms" - milliseconds • "s" - Seconds • "mins" - Minutes • "hrs" - hours • "days" - days • "years" - years • "dyears" - 10 years • "cyears" - 100 years • "ka" - 1000's of years • "dka" - 10,000's of years • "cka" - 100,000's of years • "Ma" - Millions of years
|
| Temperature Units for temperature |
Usage |
||||
|
||||
Description |
||||
Defines the units for temperature. Valid tags are: • "Celsius" - "Celsius" • "Kelvin" - "Kelvin" • "Fahrenheit" - "Fahrenheit" • "Rankine" - "Rankine"
|
| Conductivity Units for conductivity |
Usage |
||||
|
||||
Description |
||||
Defines the units for thermal conductivity. Valid tags are: • "W" - Watt
|
| Permeability Units for permeability |
Usage |
||||
|
||||
Description |
||||
Defines the units for permeability. Valid tags are: • "m^2" - Metres^2 • "D" - Darcy • "mD" - Milli Darcy • "microD" - Micro Darcy • "nanoD" - Nano Darcy • "ft^2" - Feet^2
|
| Density Units for density |
Usage |
||||
|
||||
Description |
||||
Defines the units for density. Valid tags are: • "kg/m^3" - Kilograms per cubic meter • "lb/ft^3" - Pounds per cubic feet • "lb/in^3" - Pounds per cubic inch • "lb/gal" - Pounds per galon
|
| Time_update Updated units for time |
Usage |
||||
|
||||
Description |
||||
Defines the updated units for time e.g. (s, hrs, years, Ma), for simulations where there is a change of units between stages. Valid tags are: • "ms" - milliseconds • "s" - Seconds • "mins" - Minutes • "hrs" - hours • "days" - days • "years" - years • "dyears" - 10 years • "cyears" - 100 years • "ka" - 1000's of years • "dka" - 10,000's of years • "cka" - 100,000's of years • "Ma" - Millions of years
Notes •An example of its usage is in models involving salt material where different time units are best suited to represent the initialisation and production stages (refer MEM_002 MEM tutorial example).
