zone thermal command
Syntax
- zone thermal keyword
Primary keywords:
active cmodel implicit list property property-distribution time-total zone-based-temperature
Set parameters for a thermal analysis (only available if
model configure thermal
has been specified). The following keywords apply:- active b
Sets thermal calculations on or off. The default is on after
model configure thermal
has been specified.
- cmodel keyword <range>
Associates a thermal constitutive model with specified zones in the grid. It also allows querying of properties and states of constitutive models.
- assign keyword
assigns a thermal model to all zones in the
range
. This keyword may only be given if the model is configured for thermal calculations (seemodel configure fluid
and Mathematical Model Description).- advection-conduction
Assign advection-conduction model.
- anisotropic
Assign thermal anisotropic model.
- hydration
Assign thermal hydration model.
- isotropic
Assign thermal isotropic model.
- null
Assign thermally null model.
- list
List the available thermal constitutive models and their properties.
- implicit b
Turns implicit mode on or off. By default implicit mode is off. Implicit mode requires a manually specified timestep. Note that specifying a timestep that is too large can cause the iterative matrix solver to fail to converge. (see Implicit Formulation)
- list keyword
- information
List general information about the zone specific thermal calculation settings.
- property keyword <range>
Assigns properties for the thermal constitutive models of all zones in the range. Any number of name value pairs may be assigned. Any constitutive model that has a matching property name will be assigned the value. The properties of the Advection-Conduction model are listed here, of the Anisotropic Heat Conduction model are listed here, of the Isotropic Heat Conduction model are listed here, and of the Hydration model are listed here.
- property-distribution s akeyword <range>
Assigns a single property name to the thermal constitutive models of all zones in the range. The property value may be varied in space by using the following optional keyword values.
- deviation-gaussian f
A Gaussian distribution is used to assign the value randomly, with a mean value of a and a standard deviation of f. This keyword only applies to float type property values.
- deviation-uniform f
A uniform distribution is used to assign the value randomly, with a mean value of a and a standard deviation of f. This keyword only applies to float type property values.
- gradient v <origin v >
Apply a gradient to the property value. This keyword only applies to float type property values.
- vary v
Apply a linear variation to the property value. This keyword only applies to float type property values.
- time-total f
Specifies the accumulated zone thermal time, defined as the sum of all the timesteps over which zone thermal is active. Once set, thermal time will continue to accumulate with subsequent cycles.
- zone-based-temperature b
Turns zone-based temperatures on and off. By default temperatures are calculated and stored at gridpoints, and the zone temperature is the average gridpoint value. When this is turned on, the zone temperature is stored in the zone an the gridpoint temperatures are ignored. Temperatures must be set manually using the
zone.temp
FISH intrinsic.
