Introduction: What is FLOODS/FLOOPS?
FLOOXS is a Technology Computer Aided Design (TCAD) tool used for semiconductor process modeling and semiconductor device modeling that will descretize and solve a set of partial and ordinary differential equations on a 1, 2 or 3D mesh using numerical methods such as the Finite Element Method (FEM) and the Finite Volume Method (FVM). FLOOXS is built in c++, and uses several well-known math packages such as BLAS, LAPACK, and PETSC to handle the linear algebra. The user-interface is command-line tcl (tool control language), a scripting language, with additional FLOOXS-specific Alagator commands added in.
Developers and History
Code Description
- What is Under the Hood - Detailed - A detailed description of how the c++ code is organized, how the finite element methods is implemented, what physics currently exist and how to add more.
Running FLOOXS
Installation
- Installation on Mac OSX not Lion yet - notes from v 4.1 ...
- Installation on Ubuntu 10.10 - Notes from a 64-bit Ubuntu 10.10 (Maverick Meerkat) current version FLOOXS installation with both Intel and AMD processors on 11/05/2010.
- Installation on Ubuntu - Notes from a 64-bit Ubuntu 9.10 (Karmic Koala) current version FLOOXS installation with both Intel and AMD processors on 3/29/2010.
- Installation on RedHat - (this version is outdated). Installation help and notes created as I did a clean install on a RedHat linux system. Your mileage may vary.
- Installation on Windows Linux Subsystem - Notes from Ubuntu 18.04 Subsystem on Windows 64-bit.
- Ubuntu 18.04 - See Installation on Windows Linux Subsystem, same instructions from get flooxs on.
Executing FLOOXS
- Startup Script - set environment variables and alias paths (running FLOOXS for the first time)
Overview and Basic Concepts
- Tcl - Tool Control Language is the main scripting language used to control local variables (set), do simple calculations (expr), define procedures (functions or routines), and accomplish basic read/write file operations (file). It sits on top of c++.
- Setting Parameters - how parameters work
- Alagator - Alagator is the scripting language created specifically for FLOOXS to describe the differential equations used in process and device simulation. It sits on top of tcl.
- Units in FLOOXS
Examples and Tutorials
Tutorial
- Process Tutorial - floops
- Device Tutorial - floods
If you've never used FLOOXS before, start here. Work through these examples and exercises to learn the basics of FLOOXS. The example decks here contain line-by-line explanations, and are organized in such a way as to introduce important concepts in increasing complexity. Full unannotated examples are in the full examples section.
