cornerdata
Flag to enable corner data or not, with values true or false (default). [] uses the default value.
Type: Boolean
coordsys
Coordinate system from where the results will be extracted, with values 'global' (default), 'analysis' or 'elemental'. [] uses the default value.
Supported values are:
'global'
Global default coordinate system.
'analysis'
Coordinate system in which the results were defined for each individual element.
'elemental'
Coordinate system defined from the geometry, that is, the nodal connectivity of the element.
Type: string
averaging
Averaging method, with values 'none' (default), 'simple', 'maximum', 'minimum', 'summation' and 'extreme'. [] uses the default value.
Supported values are:
'simple'
The tensors at the element corners are simply averaged.
'maximum'
The maximum value among the tensors at the element corners is considered.
'minimum'
The minimum value among the tensors at the element corners is considered.
'summation'
The tensors at the element corners are simply averaged.
'extreme'
The extreme value of the tensors at the element corners is considered.
Type: string
layer
Layer of the result (if applicable), with values 'max' (default), 'min', 'extreme', 'sum', 'average', 'range', 'count', 'maxlayer', 'minlayer', 'top' and 'bottom'. [] uses the default value.
Supported values are:
'max'
Maximum value among the layers for each entity.
'min'
Minimum value among the layers for each entity.
'extreme'
Maximum absolute values among the layers for each entity.
'sum'
(Scalar) sum of all values among the layers for each entity.
'average'
(Scalar) average value among the layers which contain data for each entity.
'range'
Difference between the maximum and minimum values among the layers for each entity.
'count'
Count of the layers for the given data type.
'maxlayer'
Layer by name that contributes to the maximum value for each entity.
'minlayer'
Layer by name that contributes to the minimum value for each entity.
'top'
Top layer.
'bottom'
Bottom layer.
Type: string

Outputs

R
Output in matrix format. The first dimension of the matrix stores the requests, the second dimension stores the different components and the third dimension stores the different time steps.
Type: matrix
