General Nodes

General nodes provide basic file operations, code execution, and template processing capabilities. These nodes are not specific to any simulation domain and can be used in any workflow.

Available Nodes

Node	Type	Description
CopyDirectory	general.CopyDirectory	Copy an entire directory to a new location
CopyFile	general.CopyFile	Copy a single file
RunOsCommand	general.RunOsCommand	Execute a system/shell command
RunPythonCode	general.RunPythonCode	Execute a Python method from a module
JinjaTransform	general.JinjaTransform	Apply Jinja2 template transformations
FilesWriter	general.FilesWriter	Write files using content from node outputs
Parameters	general.Parameters	Define general simulation parameters

Common Patterns

Chaining File Operations

{
    "nodeList": ["CopyDirectory", "RunOsCommand"],
    "nodes": {
        "CopyDirectory": {
            "Execution": {
                "input_parameters": {
                    "Source": "template_case",
                    "Target": "my_case"
                }
            },
            "type": "general.CopyDirectory"
        },
        "RunOsCommand": {
            "Execution": {
                "input_parameters": {
                    "Command": "ls -la {CopyDirectory.output.Target}"
                }
            },
            "type": "general.RunOsCommand"
        }
    }
}

Template-Based File Generation

{
    "nodeList": ["Parameters", "JinjaTransform", "FilesWriter"],
    "nodes": {
        "Parameters": {
            "Execution": {
                "input_parameters": {
                    "velocity": 10.0,
                    "viscosity": 1e-6
                }
            },
            "type": "general.Parameters"
        },
        "JinjaTransform": {
            "Execution": {
                "input_parameters": {
                    "TemplatePath": "templates/config.j2",
                    "Parameters": "{Parameters.output}"
                }
            },
            "type": "general.JinjaTransform"
        },
        "FilesWriter": {
            "Execution": {
                "input_parameters": {
                    "Files": [
                        {
                            "Path": "output/config.txt",
                            "Content": "{JinjaTransform.output.Result}"
                        }
                    ]
                }
            },
            "type": "general.FilesWriter"
        }
    }
}
