io.save_solution

io.save_solution(network, solution, path, *, dataset='Mean flow', **kwargs)

Write or append a solved network to a UI-readable YAML case.

If path does not exist, writes a fresh case (network + this solution’s datasets). If it exists, the file is expected to already hold this same network; the solution’s datasets are appended under the given dataset name so several solutions can be overlaid in one file.

Parameters

Name	Type	Description	Default
network	Network	The flow network (must match the network already stored in an existing file).	required
solution	Solution	The converged solution whose fields are embedded.	required
path	str	Destination .yaml path; appended to when it already exists.	required
dataset	str	Name for this solution’s mean-flow dataset (default "Mean flow"). Raises if a dataset of that name (or its companion chemistry dataset) is already present in the file.	'Mean flow'
**kwargs		Forwarded to :func:dump_case (e.g. fields, node_data, forced).	{}
