Implicit Disciplines

Implicit Disciplines#

Implicit disciplines are based on the discipline service, like the explicit disciplines. They also use composition and are defined as:

service ImplicitService {
    // Calls the discipline Compute function
    rpc ComputeResiduals(stream Array) returns (stream Array) {}

    // Calls the discipline RPC that solves the nonlinear equations
    rpc SolveResiduals(stream Array) returns (stream Array) {}

    // Calls the discipline ComputePartials function
    rpc ComputeResidualGradients(stream Array) returns (stream Array) {}
}

ComputeResiduals#

The ComputeResiduals function evaluates the residual given a set of inputs.

SolveResiduals#

The SolveResiduals function solves the residual (drives it to zero) and returns the discipline outputs for that state.

ComputeResidualGradients#

The ComputeResidualGradients function computes the derivatives of the ComputeResiduals function.
