The surface needs some defined condition (e.g. Isobaric) This module defines how the surface is defined. Again, much like the deformation system this does not actually implement much of the code to deform the surface to that condition; rather, it implements code to allow the prescription to be described robustly at compile time
The model must be able to deform to capture the shape induced by rotation or an external potential. Here we add the precription to descibe how we allow deformation. Note that the code to define how deformation is actually implemented is in the backend.
Broadly MeanField had a system that would map the full index of degrees of freedom to some reduced index space based on domain support. This system has been cleaned up and ported. Further, we have consolidated this system into the discretization system from where it lived in MeanField (in the operators subsystem)
most (though not all) of the runtime eos code is now present in the new version. What remains is the templated try_evaluate method along with both the templated and non tempalted try_partial_derivative methods.
The full rewrite of mean_field into something maintainable is progressing. dimensions is mostly done, discritization (domain, blocks, and fields) is done, and eos is progressing quickly
