Meshes
Ants input and output fields are based on a few different meshes.
Input node mesh
Calculation node mesh
Input node pin mesh
A two level mesh where the first level corresponds to the input node mesh, while the second level is a list of the different pins inside the input node.
Calculation node pin mesh
A two level mesh where the first level corresponds to the calculation node mesh, while the second level is a list of the different pins inside the input node.
Microdepletion mesh
A two level mesh where the first level corresponds to the calculation node mesh, while the second level is a list of the different nuclides in the calculation node.
