Network Region Reference

A network region represents the thermal network for a manikin in a thermal comfort simulation. A thermal network computes the thermo-physiological responses of a human body.

To create a network region, right-click the Regions node and select New > Network Region.

Network Region Properties

Physics Continuum
Selects the thermal network physics continuum that contains the selected thermal comfort models such as a Fiala Thermoregulation model or the Equivalent Homogeneous Temperature model.
Parts
Selects the manikin geometry part for which thermal comfort is to be predicted.
Type
Is set to Thermal Network Region as the only option.
Topology
Network (read-only)

Network Region Right-Click Actions

Create Interface
You multi-select the network region and another fluid or solid region to create a thermal network interface.

Boundary Settings

Thermal Network Boundary
The default thermal network boundary is created automatically upon creation of the thermal network region.
Part Surfaces
Selects the geometry part surfaces of the manikin for which the thermal network is computed.
Type
Is set to Thermal Network Boundary, which is the only option available.
Topology
Surface (read-only)
Thermal Network Interface Boundary
Is created when a thermal network interface has been created.
Type
Thermal Network Interface Boundary, the only option available.
Topology
Surface (read-only)
Parent Interface
The interface that created this boundary (read-only).

Region Settings

The following physics conditions and values appy to a thermal network region.
Ambient Relative Humidity
For the Fiala Thermoregulation models only. Specifies the relative humidity of the surroundings of the manikin (in percent).
Manikin Part Groups > [manikin]
Associates the thermal network region with the manikin geometry part for which thermal comfort is to be predicted.
Parts
Selects the manikin geometry part.
Network Links
For the Fiala Thermoregulation models only. Contains one sub-node for each of the 58 manikin sectors that represent the sub-divided body parts: Head_Top, Head_Back, Face_R, Face_L, Neck_Back, Beck_Front_R, Neck_Front_L, Thorax_Back, Thorax_Front_R, Thorax_Front_L, Abdomen_Back, Abdomen_Front_R, Abdoment_Front_L, Pelvis_Bottom, Pelvis_R, Pelvis_L, L_Shoulder, R_Shoulder, L_Arm_Front_R, L_Arm_Front_L, L_Arm_Back_R, L_Arm_Back_L.
Part Surfaces
Selects the manikin geometry part surface that is associated with the network link.
EHT Segments
For the Equivalent Homogeneous Temperature model only. Contains one sub-node for each of the 17 manikin segments that represent the body parts: R_Foot, L_Foot, R_Calf, L_Calf, R_Thigh, L_Thigh, R_Hand, L_Hand, R_Forearm, L_Forearm, R_Arm, L_Arm, Thorax_Back_and_Shoulders, Thorax_Front, Face_and_Neck, Head, Abdomen_and_Pelvis.

Interface Settings

The following interface is available only in combination with a thermal network region.

Thermal Network Interface
To create a thermal network interface, multi-select a thermal network region and another solid or fluid region, then right-click the selection and choose Create Interface.
Geometry
Set to Contacts (read-only).
Contacts
Selects the contacts between the manikin part surfaces and the part surfaces of the fluid or solid region. For example, the fluid region can be the air in a vehicle cabin and the solid region can be a seat on which the passenger sits.
Type
Thermal Network Interface
Topology
Indirect is the only option available.

A thermal network interface has the following physics conditions and values.

Clothing Evaporative Resistance
A measure for how much the clothes pose a resistance to the sweat that evaporates from the body of the manikin to the environment. The value is for the entire manikin body, specified in in Pa-m2/W. A low value for the evaporative resistance corresponds to high evaporation.
Contact Resistance
The thermal insulation effect of clothes. A constant value is for the entire manikin body, specified in m2K/W. Another unit that is used in industry in clo. 1 clo = 0.155 m2K/W. A value of clo = 0 corresponds to bare skin, a value of clo = 1 corresponds to the amount of clothing that is needed to keep a person comfortably at rest at room temperature of 21 ℃ with relative humidity of 50%.
