Detailed Description
im_data provides indexing to the integration points of a mesh im object.
The im_data data contains a reference of mesh_im object . The index can be filtered by region, and each im_data has its own tensorial size.
Filtered methods will provide filtered index on the region. This class also provides reading and writing tensor( including matrix, vector and scalar) from a vector data (generally a fixed-size variable from the model.)
im_data can be used to provide integration point index on convex or on faces of convex, but not both. To create an im_data that represents integration points on a face, the filter region provided has to contain only faces.

Constructor.
- Parameters
-
mim Reference mesh_im object tensor_size tensor dimension of each integration points filtered_region index not in the region will be filtered out. If filtered_region can contain only convexes or only faces or both convexes and faces. Actual_tensor_size the actual size of the tensor the data represents. Used for example, for a Voigt annotated data.

Constructor.
The tensor size by default is a scalar value.
- Parameters
-
