Availability

Version 1.0 of Larry3D is included in the 2.0 release of the SEATREE package.

Requirements

A Fortran compiler, such as gfortran.

Installation

Larry3D is installed automatically using the development version of the ​SEATREE configuration and installation utility.

Larry3D can be installed manually by changing into the SEATREE subdirectory where larry3d resides, and typing "make".

Documentation

Use of Larry within the Seatree environment is described in the Seatree user documentation.
