In Openoil3D: Getting Error: 'OilProps' object has no attribute 'oil_water_surface_tension' Why I am getting this issue. Please Help to Resolve the error.. Thanks in Advance!!!

Probably your version of NOAA OilLibrary is outdated. Please update both OpenDrift and OilLibrary to the latest versions, to ensure compatibility. Note that OilLibrary needs to be recompiled with python setup.py remake_oil_db after updating the code.

Dear authors, When testing the oillibrary, i have the problems: FAIL: test_dispersion (main.TestOil) Traceback (most recent call last): File "C:/opendrift-master/tests/test_oillibrary.py", line 92, in test_dispersion fraction_dispersed) AssertionError: 0.09339651 != 0.068167008 within 7 places

====================================================================== FAIL: test_droplet_distribution (main.TestOil) Traceback (most recent call last): File "C:/opendrift-master/tests/test_oillibrary.py", line 130, in test_droplet_distribution self.assertAlmostEqual(d.mean(), 0.00006904389) AssertionError: 5.763371939835245e-05 != 6.904389e-05 within 7 places

Would you please to help me?

Maybe you have an old version of either software? You may check version numbers by:

>>> import opendrift
>>> opendrift.__version
'1.0.3'
>>> import oil_library
>>> oil_library.__version__
'1.0.6'

These are the latest versions, which should work well together.

[HanhHelen]

I have these version. I don't know why ???

[knutfrode]

Is this the only test which fails?

Can you paste here the full output you get when running the test test_oillibrary.py ? (or send the complete output from testall by email to knutfd@met.no)

[HanhHelen]

This is the output when I run the test test_oillibrary.py:

I also have the same problem with the test_stranding.py. So from testall I have: Output of testall.docx

Hope you can find out what happened.
