TGM about Tensors and SymmetricTensors in 4C

[amgebauer]

In the last weeks, I worked on an implementation of Tensors. Since the implementation is now in a good shape, we can use it in a broader context, I want to make a short presentation of how to use the newly introduced Tensor and SymmetricTensor-classes. The content will be:

• Why do we need Tensors in 4C? What is the indented use-case?
• How to use Tensors and SymmetricTensors and their view-classes (definition, overview of tensor operations, interplay with Matrix and Voigt-notation)
• Performance considerations
• Automatic differentiation with tensors
• Discussion

In the TGM, we can also discuss the interface of the tensor since now we can still change it easily, but it will become more and more difficult once it emerged into the codebase.

To find a suiteable time-slot, please indicate your availability by reacting to the respective comment in this discussion until this week on Friday (June 20). Short notice, but the TGM will be recorded, as usual.
