Orcaflex Static Debug Minimal Reproducible Model

Minimal Reproducible Model (+1)

Minimal Reproducible Model

When debugging, create a stripped-down model that isolates the failing component:

import OrcFxAPI

def create_minimal_debug_model(failing_model_path, suspect_line_name):
    """Create a minimal model with only the suspect line for debugging."""
    model = OrcFxAPI.Model()
    model.LoadData(failing_model_path)

    # Remove all lines except the suspect
    for obj in list(model.objects):
        if obj.typeName == "Line" and obj.name != suspect_line_name:
            model.DestroyObject(obj)

    # Simplify environment
    env = model.environment
    env.WaveType = "None"

    # Save debug model
    debug_path = failing_model_path.replace(".yml", "_debug.yml")
    model.SaveData(debug_path)
    return debug_path
