NonlinearSystem

Source: es/system.py

A nonlinear system defined by a Model.

Other options

model — str · required

The Model defining this nonlinear system.

unknowns — list · required

Ordering and grouping of unknowns. Each inner list defines one variable group.

residuals — list

Ordering and grouping of residual variables. Each inner list defines one variable group.

structure — list

Per-group SubBatchStructure (‘block’ or ‘dense’). One token per group, in group order. Mirrors v2’s istructure = 'BLOCK DENSE'. BLOCK preserves sub_batch axes as intmd dims on the per-group assembled tensor (per-grain / per-cell / per-bin independence stays compact). DENSE folds sub_batch into base. Defaults to all ‘dense’ when omitted.
