Status: Answered => Open
behzad is still having a problem:
I just find no way to get this thing working. Even with globals it gives
an error!
TW=TesselationWrapper()
TW.triangulate()
TW.computeVolumes()
global xy
xy=[]
for i in O.bodies:
if isinstance(i.shape,Sphere):
xy.append(i.state.pos[0])
vtkExporter = export.VTKExporter('Rep')
vtkExporter.exportSpheres(what=[('xDist','globals()["xy"][b.id]')])
output:
Traceback (most recent call last):
File "/home/bemaj3/sw/bin/yade2015", line 182, in runScript
