Export x,y,z data

Asked by Nikos Chamakos

Hello yade community!

Is it possible to export the simulation data in the following form?

x_coordinate, y_coordinate, z_coordinate, radius
.
.
.

where x_coordinate, y_coordinate, z_coordinate are the coordinates of the particles' center.
I want to import them in a mesh software in order to generate an unstructured mesh around the particles.
I tried to open the saved xml file, however, is too large in my case (~2GB).

Thanks for your answer!
Nikos

Hello,

sure. The easiest way is to use predefined function for that [1]:
###
# some code generating packing you want
from yade import export
export.text("someFileName.dat")
###

cheers

Thanks for your answer!

Can I do that in the yade terminal? Since I have already performed the simulations.

I gives me the following error:

Yade [1]: export.text("xyzdata.dat")
---------------------------------------------------------------------------
NameError Traceback (most recent call last)
/usr/bin/yade in <module>()
----> 1 export.text("xyzdata.dat")

NameError: name 'export' is not defined

Thanks again
Nikos

sure (see my previous answer):
###
from yade import export # ! important
export.text(...)
###
or
###
yade.export.text(...)
###
