Hello, everyone.
I made a sample of the particles before the model was run. After the sample
preparation, I want to import the particles through the example provided by
script [1]. I ran the following three lines in the program:
#########################################
>From Yade import export
VtkExporter = export. VTKExporter ('/tmp/vtkExporter Testing')
VtkExporter. exportSpheres (what = Dict (dist ='b. state. pos. norm ()')
#########################################
However, after the operation, the following errors occurred:
ValueError Traceback (most recent call last)
/usr/bin/yadedaily in <module>()
----> 1 vtkExporter.exportSpheres(what=dict(dist='b.state.pos.norm()'))
/usr/lib/x86_64-linux-gnu/yadedaily/py/yade/export.py in exportSpheres(self,
ids, what, comment, numLabel, useRef)
428 outFile.write("%g\n"%(b.shape.radius))
429 # write additional data from 'what' param
--> 430 for name,command in what: # for each name...
431 test = eval(command) # ... eval one example to
see what type (float, Vector3, Matrix3) the result is ...
432 # ... and write appropriate header line and
loop over all bodies and write appropriate vtk line(s)
ValueError: too many values to unpack
#########################################
I would appreciate it if you could give me some advice.
