使用flopy从MODFLOW-USG二进制输出中提取报头

Question

我正在寻找一种从MODFLOW-USG二进制头部保存文件中提取模拟头部的方法。Flopy似乎支持使用flopy.utils.binaryfile模块的操作，但我不能让一个简单的测试工作。下面的代码应该返回hds文件中包含的所有时间输出的列表，但只返回第一个时间步长的单个值。flopy是否支持从非结构化网格head-save文件中提取数据？

modelname = 'Torr_TRu'

import flopy.utils.binaryfile as bf

# Create the headfile object
headobj = bf.HeadFile(modelname+'.hds')
times = headobj.get_times()
print times

Answer 1

flopy有一个方法(.HeadUFile())用于读取使用DISU包的MODFLOW-USG模型的结果。来自MODFLOW-USG提供的01A_nestedgrid_nognc示例。

>>> import flopy
>>> hobj = flopy.utils.HeadUFile('flow.hds')
>>> hobj.get_times()
[1.0]
>>> hobj.get_kstpkper()
[(0, 0)]
>>> hobj.get_data()
