在Jmodelica中使用Dymola导出FMU仿真并更改参数

Question

如果我使用Jmodelica编译模型，然后加载FMU并更改参数，就可以了。

但是相同的型号，我使用Dymola出口的FMU， 然后我将这个FMU文件加载到Jmodelica中，更改参数失败。

from pymodelica import compile_fmu
from pyfmi import load_fmu
from pyjmi.common.plotting import plot_gui
my_fmu=
'D:\MoPath\Buildings_Fluid_Boilers_
Examples_BoilerPolynomialClosedLoop.fmu'
vdp = load_fmu(my_fmu)
vars = ['Q_flow_nominal']
values = vdp.get(vars)
values = 40000.0
vdp.set(vars, values)
res = vdp.simulate(final_time=240*60)
plot_gui.startGUI(res)
