Hello,

> Does using batch file mean I can divide the simulation into 2 parts?
No.
Batch run in Yade context means that you run the same script multiple times
with given (usually varying) parameters.
E.g. you could run your simulation with varying value of gravity (artificial
example) with values 9.81, 20, 100 and 500.
Batch run can be run all jobs sequentially or all jobs in parallel or a
combination of both.
The main advantage is simplicity of the setting.
> I'm couldn't understand what exactly is readParamsFromTable(damping
=.2)
readParamsFromTable reads parameters from table if given, otherwise it
uses default value (damping=0.2 in this case)
For the gravity example above, you can create the "grav.table" file:
### grav.table
gravity
9.81
20
100
500
###
### script.py
readParamsFromTable(
gravity = 9.81,
)
from yade.params.table import *
print(gravity)
###
and then run it as
yade-batch grav.table script.py
Cheers
Jan
