Try out the improved Leiden Classical-Builder 2.01

As of April the 27th of 2011, the ClassicalBuiler can directly submit to the LGI (Leiden Grid Infrastructure) backend.

This allows students in Leiden to run classical jobs not only through BOINC on the Desktop grid; but also on BigGrid resources, our local clusters and on the national supercomputers.

Special thanks to Willem van Engen and Jan Just Keijser of NIKHEF for this!

Please check out the forum too.


Classical-Builder was developed to create input files for the program Classical. Classical Builder allows you to
create particles, use multiple interactions and define constraints between two or more particles. You can create these
particles in a Java3D environment using both 2D and 3D view screens.
