CAE Reader 3D

Use the CAE Reader 3D to import and work with CAE test data.

The CAE Reader 3D leverages Altair CAE readers provided with Compose that require access to model information, such as corner data, averaging method, layer, and coordinate system to import and read in CAE data without the need of a translator or converter.

Supported Files and Formats

Time and frequency-based data formats.
Files generated with Finite Element method, Computational Fluid Dynamics, and Multibody System solvers.
File formats: .H3D, .ODB, .OP2, and others.

CAE Reader 3D Options


Option	Description
File	Navigate to the CAE file that you want to load.
Subcase	Select a subcase for the specified CAE file.
Type	Select a result type based on the specified subcase.
Search box	Type a string to search in the requests, components, and timesteps. You can use regular expressions with wildcards like * or Match Case.
Requests	Choose an option to enter requests: Select the Selection button, then choose one or more of the requests that are available for the specified file. Select the All checkbox to specify all of the requests. Select the List button, then enter a list of requests. The format of the list should be separated by: Comma: delimits different requests. Colon: delimits ranges of requests. For example using indices: `100,200,213:215,300` or using the names of the requests: `'N1','N3','N10':'N14','N17'` will query the following list of requests: N1 N3 N10 N11 N12 N13 N14 N17
Components	Select one or more components based on the specified subcase and result type. Select components of interest. Select All to select all components.
Corner date	Choose corner data option. Supported options are only, true, or false.
Averaging	Choose the Averaging method. Averaging method supported values are: 'None' '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. 'advanced': The tensors at the element corners are advanced averaged.
Analysis	Coordinate system that is used to calculate the results. 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.
Layer	Layer of the element. 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. Any Layer name is returned by getlayername3d.
Plot Style	Choose Line or Scatter. Note: If you select one request, one component, and many timesteps, the scatter plot style is used by default to differentiate the time step data.
Print	Select the Print button to enable the importing of the data. The command generated can be used within any script. The size of the expected output of the Print command is displayed in the message bar: `Output of Print command will have size 4x3x1` which represents the size of a matrix output as [Requests x Components x Time Steps].
Preview	Select the Preview button and review the defined line or scatter plot, which is 2D or 3D depending on the number of specified requests, components and time steps. One request, multiple components and multiple time steps: a 2D plot is generated with time steps displayed in the X axis and curves displayed for the different components. Multiple requests, one component and multiple time steps: a 2D plot is generated with time steps displayed in the X axis and curves displayed for the different requests. Multiple requests, multiple components and one time step: a 2D plot is generated with requests displayed in the X axis as indices and curves displayed for the different components. Multiple requests, multiple components and multiple time steps: a 3D plot is generated with requests displayed as indices in the X axis, curves displayed for the different components in the Y axis, and time steps displayed in the Z axis.
Import	Select the Import button, then import data into the workspace with the name `data`. Note: If a `data` variable already exists in the workspace, the software prompts you to confirm if the variable should be overwritten or not.
