In the case when Static is
on a static linearized model of the system is described by
Let Null be the PDE constraint null-space matrix and
ud a particular solution fulfilling the constraints. The solution vector
U for the problem can then be written
where u0 is the linearization point, which is determined by the current solution (that is, the solution computed by the previous feature in the sequence). The previous feature can, for example, be a solver or a Dependent Variable node. The Dependent Variable node gives control over which variables to solve for (compute the matrices for). The input linearization point is stored in the sequence after the state-space feature is run.
The input parameters input should contain all parameters that are of interest as input to the model. The output expressions
output should contain a list of all expressions that are to be evaluated as output from the model.
