readcae3d

Reads data from a given file using the 3D CAE Readers. readcae3d uses the CAE readers provided with Activate that require access to model information, such as corner data, averaging method, layer and coordinate system.

Attention: Available only with Activate commercial edition.

'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

Comments

The result files coming from the following simulations are not supported yet: - Multibody Simulation - RADIOSS - abstat

Coordinate system is not applicable for scalars and is ignored with a user warning.

Averaging method is not applicable for vectors and is ignored with a user warning.

Layer is not applicable for vectors and is ignored with a user warning.

Corner data is not applicable for scalars. An averaging method should be given if corner data is set to true.
