Coupled simulations

[dbeurle]

Including multiphysics will be essential for interactions between mechanical and diffusion processes. This requires a robust way of transferring data between the modules to avoid excessive memory copying.

Requirements

This feature requires new infrastructure in the preprocessor to schedule the simulations. The requirements of this structure are:

• Propagation of results through multiple cases
• Apriori error checking. This will require construction of objects and checking inputs
• Arbitrary mixing of modules (mechanical followed by diffusion for example)
• Efficient access to internal variables and solution vectors to avoid excessive memory copies of large structures

Proposed implementation

An algorithm for scheduling the simulations is required, as a particular module may have multiple steps, where the steps reuse the previous simulation state. The scheduling model must be generic enough to handle a combination of procedures.
