# zone thermal command

Syntax

zone thermal keyword

Primary keywords:

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 (see model configure fluid and Mathematical Model Description).

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>
List the values of all thermal properties matching the property in the range.
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.

Add a to the property value. This keyword only applies to float type property 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.

Apply a gradient to the property value. This keyword only applies to float type property values.

multiply

Multiply the property value by a.

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.
