Trim.SP - TRIM simulation

This repository contains the Fortran source code and an accompanying graphical user interface (GUI) for TrimSP - an application for performing Monte Carlo simulations of ion implantation.

This code is specifically tuned to simulate implantation of low-energy projectiles in materials.
The code is maintained by the Low Energy Muons (LEM) group at the Paul Scherrer Institute (PSI).
The GUI is written in Node.js, JavaScript and Electron.
The binary (statically linked) from the Fortran code is also included.
RPM and DEB packages are also included.

Installation

For a simple installation you may use the included RPM or Debian packages which come with statically linked binaries. See instructions below if you prefer a manual installation.

Fortran code compilation

Install the gfortran compiler, then:

cd trimsp/fortran
make
make install

This will install the trimspNL binary in /usr/local/bin, but it can be moved to any other directory in your PATH.

Running the GUI

Install Node.js (nodejs, nodejs-libs and npm), then run:

cd trimsp
npm install
npm start

Note: you do not need to run npm install every time. Next time you can simply run npm start only.

Deploying on a web server

The browser version requires a server-side setup in addition to the static HTML/JavaScript files.

In particular:

the browser build uses TrimSPweb.js rather than the Electron-specific TrimSPelec.js
the simulation backend must be available on the server
a web-exposed helper/CGI layer is required to create input files, run the backend, and return the generated output

Notes:

this repository does not currently include the CGI/backend helper used by the online deployment
a plain static web server is therefore not sufficient for running web simulations from this checkout
static hosting can still be used to test page loading only
