trento's Issues

auto grid

trento should automatically choose a reasonable grid size based on the collision system. Right now the default is 10 fm regardless of the system, which is ridiculously large for pp and pA. It's very easy to forget to reduce the grid size when switching systems.

trento classes already have enough information to do this, so it should be easy.

The --grid-max option would of course remain as a user override.

Error while building trento code

Dear Sir,

I have installed " Boost". And I am trying to build trento. The terminal message of cmake .. in the build folder is the following:

-- The CXX compiler identification is GNU 9.3.0
-- Detecting CXX compiler ABI info
-- Detecting CXX compiler ABI info - done
-- Check for working CXX compiler: /usr/bin/c++ - skipped
-- Detecting CXX compile features

-- Found Boost: /usr/local/lib/cmake/Boost-1.77.0/BoostConfig.cmake (found suitable version "1.77.0", minimum required is "1.50") found components: filesystem program_options system

-- Build type: Release
-- Install prefix: /home/kakashi/.local
-- Configuring done
-- Generating done
-- Build files have been written to: /home/kakashi/ALL_CODES/trento-master/build

(I did not install the HDF5 dependency as it was optional.)
And then after make install, I get the following:

I tried search for this error but couldn't solved it.
I tried installing trento in another computer, but I received the same error.
Could you please help me resolve this.

TrENTo Website Unreachable

The TrENTo link has been updated to point to the TrENTo GitHub repository while the TrENTo website remains unreachable. This issue is a reminder to restore the TrENTo website link when the site is again available.

deuteron

trento needs a deuteron projectile type in order to model d+Au collisions at RHIC. This should be fairly straightforward: just sample a radius from the Hulthén wavefunction as described in the PHOBOS Glauber model.

better docs

The README is just a placeholder. This is a reminder to complete the actual sphinx-generated documentation site.

auto cross section

Currently, trento requires the user to explicitly set the cross section. This is annoying, since the cross section changes with beam energy and the experimental values are sometimes hard to find.

The interface should provide a --beam-energy option, and the code should interpolate a set of experimental points and choose an appropriate cross section. The --cross-section option would still be available to allow the user to override the interpolation.
