问题描述
我想借助 OMPython 在 Python 中模拟 OpenModelica 模型。以下是我的代码：
import matplotlib.pyplot as plt
import OMPython
from OMPython import OMCSessionZMQ
from OMPython import ModelicaSystem
omc = OMCSessionZMQ()
mod = ModelicaSystem("Li_ionBattery.mo","Li_ionBattery.TestBench.varyingCurrent")
Li_simulation = mod.getSimulationoptions()
mod.setSimulationoptions(["stopTime=2000","stepSize=50"])
variables_vary = mod.getQuantities()
Parameters_vary = mod.getParameters()
continous_vary = mod.getContinuous()
mod.setParameters(["nMC_Data.Q_nom=11","nMC_Data.Rs=0.0003"])
mod.simulate()
我收到以下错误：
Notification: Li_ionBattery requested package Modelica of version 3.2.2. Modelica 3.2.3 is used instead which states that it is fully compatible without conversion script needed.
Error: Class Li_ionBattery.TestBench.varyingCurrent not found in scope <top>.
Error: Class Li_ionBattery.TestBench.varyingCurrent not found in scope <TOP>.
stopTime !is not a simulation-option variable
Traceback (most recent call last):
raise Exception("Error: application file not generated yet")
Exception: Error: application file not generated yet
我无法理解这个问题，请帮我解决这个问题，因为我是 Python 新手。谢谢你
解决方法
错误在一行，
mod = ModelicaSystem("Li_ionBattery.mo","Li_ionBattery.TestBench.VaryingCurrent")
据报道，
Error: Class Li_ionBattery.TestBench.VaryingCurrent not found in scope <top>.
确保 Li_ionBattery.TestBench.VaryingCurrent 类存在于 Li_ionBattery.mo 中。
