如何在Flopy创建的MODFLOW输出中跟踪错误

Question

几个星期以来，我正在用Python用Flopy编写MODFLOW模型。由于Python的透明性，我选择用Flopy编写模型。但是，有时我的模型无法运行，但无法告诉我哪里出了问题，这使错误处理变得困难。

此刻，我的模型在运行模型时出现错误。我手动添加的消息（通常使用）会引发错误：

success, mfoutput = mf.run_model(silent=False, pause=False) 
if not success:
    raise Exception('MODFLOW did not terminate normally.')

我得到的错误是：

FloPy is using the following  executable to run the model: /usr/bin/mf2005

                                  MODFLOW-2005     
    U.S. GEOLOGICAL SURVEY MODULAR FINITE-DIFFERENCE GROUND-WATER FLOW MODEL
                             Version 1.12.00 2/3/2017                        

 Using NAME file: spangen_mod.nam 
 Run start date and time (yyyy/mm/dd hh:mm:ss): 2019/04/23 16:12:39

Traceback (most recent call last):

  File "<ipython-input-85-c7ecca798eed>", line 1, in <module>
    runfile('/Users/user/Desktop/modflow/model.py', wdir='/Users/user/Desktop/modflow')

  File "/Users/user/anaconda3/lib/python3.7/site-packages/spyder_kernels/customize/spydercustomize.py", line 704, in runfile
    execfile(filename, namespace)

  File "/Users/user/anaconda3/lib/python3.7/site-packages/spyder_kernels/customize/spydercustomize.py", line 108, in execfile
    exec(compile(f.read(), filename, 'exec'), namespace)

  File "/Users/user/Desktop/modflow/model.py", line 223, in <module>
    raise Exception('MODFLOW did not terminate normally.')

Exception: MODFLOW did not terminate normally.

此外，将创建所有MODFLOW文件，但.hds和.cbc文件包含零字节。

我的问题：有人有技巧来高效，智能地找到这类错误。
