Manikin Model Reference

The Fiala Thermoregulation models and the Equivalent Homogemeous Temperature model represent the human bodies with manikins.

The manikin is a geometry part that you import. The Manikin model applies properties that influence the body heat loss to the manikin—for the Fiala Thermoregulation model, this is the activity level, for the Equivalent Homogemeous Temperature model, these are the linearization coefficients of the model.

A manikin is subdivided into a certain number of segments, depending on the model that is used:
  • For the Fiala Thermoregulation models, the manikin is subdivided into 20 segments and 58 sectors during geometry preparation. Each of the sectors correspond to a part surface of the manikin geometry.
  • For the Equivalent Homogemeous Temperature model, the manikin is subdivided into 17 segments. Each of the segments correspond to a part surface of the manikin geometry.

For more information, see Splitting the Manikin into Segments and Manikin Segmentation Naming Convention Reference.

This node contains the property nodes for the nth manikin. The Fiala and Equivalent Homogeneous Temperature manikins have different properties:
Fiala Manikin Properties
Activity Level (met)
Metabolic activity level of the manikin. The activity level is used to calculate the metabolic heat rate production of the manikin as the ratio of the heat that the manikin generates at that activity level to the average metabolism when seated. The activity level is measured in the dimensionless unit met. 1 met = 58 W/m2, which corresponds to a seated manikin. The default value is 0.8, which corresponds to a reclining manikin at rest.
Height
Height of the manikin in meters. The default is 1.9096. (Read-only)
Weight
The weight of the manikin in kilograms. The default is 73.4. (Read-only)
Age
Age of the manikin in years. The default is 35.0. (Read-only)
Gender
Sex of the manikin.The default is unisex. (Read-only)
EHT Manikin Segment Properties
The EHT manikin is composed of 17 segments. Each segment has the same two properties, x0 and x1.


x0 and x1
x 0 and x 1 in Eqn. (1803) are the linearization coefficients of the EHT algorithm. The default values have been taken from the linearization of the heat transfer coefficients using calibration simulations, performed by Rommelfanger et al. [418].

If a constant value for the heat transfer coefficient is to be specified, x0 can be set to 0 and x1 can be set to the required heat transfer coefficient value.
