ValueError: setting an array element with a sequence

Asked by Yor1

Hello Yade users,

I try to sample my microcracks to determinate the acoustic event during the simulation.
To reach my goal, i wrote a script "cracks_sampling.py". In the beginning of the script i try to import the microcracks data.
But i run the script, i obtain this error message :" ValueError: setting an array element with a sequence".
I understand that the origin of the problem is my microcracks data but i don't what i have to do to overcome this problem knowing that my microcracks data is 6.4 Mo.

You can download the script from this link : https://filex.univ-lorraine.fr/get?k=xyFvdVA5UVm4mF1Rr11
You can download the cracks data from this link : https://filex.univ-lorraine.fr/get?k=rmY3BBKtB9Vk9r6ryqT

Best regards.
Jabrane.

Hi Jabrane,

please provide a consistent script and .txt data. In this example I got either
IOError: [Errno 2] No such file or directory: 'cracks_X6Y12Z6_notch_compressionTest_0MPa_bis.txt'
or with "cracks_...0MPa.txt":
ValueError: Wrong number of columns at line 470

cheers
Jan

Hi Jan,

Thank you for the response.
In fact, I got the problem and i resolve it this morning.
The origin of the problem is the manner of editing the txt file in the sources files (JointedCohesiveFrictionalPM.cpp).
For the traction cracks, these parameters are edited : iteration, X, Y, Z, Norm0, Norm1, Norm2, traction, shear Aperture, Time, Energy.
But for the shear cracks, just these parameters are edited : iteration, X,Y,Z, Norm0, Norm1, Norm2, traction, shear Energy.
So the error message is correct because i try to insert vectors of 10 element with vectors with 12 element.
I corrected this mistake of data editing.
And the script work very well.

Best regards.
Jabrane.
