EffortMeasure
Measures the energy consumption of a model during simulation, according to various models.
Supported effort models:
Constant
: constant energy measureTotalForce
: total muscle forceWang2012
: metabolic energy measure as defined in [Wang et al. 2012]Uchida2016
: metabolic energy measure as defined in [Uchida et al. 2012]SquaredMuscleStress
: summed squared muscle stress: (force / PCSA)^2SquaredMuscleActivation
: summed squared muscle activation: (activation)^2
This can also be used for cost-of-transport, using the use_cost_of_transport
parameter.

Public Attributes
Parameter | Type | Description |
---|---|---|
measure_type | EnergyMeasureType | Energy model to be used, can be: TotalForce , Wang2012 , Uchida2016 , or Constant ; default = UnknownMeasure . |
use_cost_of_transport | bool | Flag indicating to use (energy / distance) as a result; default = 0. |
specific_tension | Real | Value to use for specific tension; default = 0.25e6. |
muscle_density | Real | Value to use for muscle density; default = 1059.7. |
default_muscle_slow_twitch_ratio | Real | Default slow / twitch ratio if not defined per muscle (used by Uchida2016); default = 0.5. |
use_symmetric_fiber_ratios | bool | Indicate if fiber ratios are the same for left and right (used by Uchida2016); default = true. |
min_distance | Real | Minimum distance used for cost of transport computation; default = 1.0. |
name | String | Name of the Measure, to be used in reporting; defaults to measure type. |
weight | Real | Weighting factor applied to the result of the measure; default = 1. |
threshold | Real | Threshold above / below which the measure becomes zero; default = 0. |
threshold_transition | Real | Transition range above threshold between which the measure linearly decreases to zero; default = 0. |
result_offset | Real | Offset added to measure result; default = 0. |
minimize | bool | Indicate whether this measure should be minimized; default value depends on the measure type (usually true). |
start_time | TimeInSeconds | Time [s] at which Controller becomes active; default = 0. |
stop_time | TimeInSeconds | Time [s] at which Controller becomes inactive; default = until simulation ends. |
signature_prefix | String | Prefix signature with custom string. Special tags: DATE_TIME, DATE_TIME_EXACT, SCONE_VERSION. |
signature_postfix | String | Append custom string to signature. Special tags: DATE_TIME, DATE_TIME_EXACT, SCONE_VERSION. |
