In addition to the inputs shown above, some optional properties may also be specified. They can be viewed here.

If kinetic reactions are defined in the chemistry model, kinetic calculation inputs are required to be specified. A detailed description can be found here.

Response (status = PROCESSED)

The output of this calculation is the stream output which is common result output for all OLI's flash calculations or an error.
