PIPESIM Python Toolkit 系列(14)：管网模拟——边界条件设置与批量运行

管网模拟（Network Simulation）是 PIPESIM 最核心的功能。PTK 通过 tasks.networksimulation 模块提供完整的模拟流程控制——从边界条件设置到结果提取，全部可编程化。

获取当前边界条件

conditions = model.tasks.networksimulation.get_conditions()
# 获取特定 Study 的条件
late_life = model.tasks.networksimulation.get_conditions(
    study="Late Field Life")

设置边界条件

from sixgill.definitions import Parameters, Constants
boundaries = {
    "Well:VertComp": {
        Parameters.Boundary.PRESSURE: float('nan'),
        Parameters.Boundary.TEMPERATURE: 150,
        Parameters.Boundary.FLOWRATETYPE:
            Constants.FlowRateType.LIQUIDFLOWRATE,
        Parameters.Boundary.LIQUIDFLOWRATE: 200
    }
}
model.tasks.networksimulation.set_conditions(boundaries=boundaries)

运行模拟

关键性能提示：务必明确指定所需的系统变量和剖面变量！不指定时 PTK 会返回全部变量，严重影响性能。文章源自云智设计-https://www.cidrg.com/cid-college/tutorial/pipesim/26878.html

from sixgill.definitions import SystemVariables, ProfileVariables
system_vars = [
    SystemVariables.PRESSURE,
    SystemVariables.TEMPERATURE,
    SystemVariables.VOLUME_FLOWRATE_LIQUID_STOCKTANK,
    SystemVariables.BOTTOM_HOLE_PRESSURE,
]
profile_vars = [
    ProfileVariables.TEMPERATURE,
    ProfileVariables.ELEVATION,
    ProfileVariables.TOTAL_DISTANCE,
]
results = model.tasks.networksimulation.run(
    system_variables=system_vars,
    profile_variables=profile_vars)

带自定义条件的模拟

results = model.tasks.networksimulation.run(
    boundaries=boundaries,
    system_variables=system_vars,
    profile_variables=profile_vars)

这种"一次性传参"模式特别适合批量工况的排队模拟。文章源自云智设计-https://www.cidrg.com/cid-college/tutorial/pipesim/26878.html 文章源自云智设计-https://www.cidrg.com/cid-college/tutorial/pipesim/26878.html
