Overview

All the software available from this download page is related to RAMSES. RAMSES is an acronym for Research Aids for Modeling and Simulation of Environmental Systems. Visit the RAMSES home page to learn more about it. All functionality provided by RAMSES is fully documented and available for web browsing from RAMSES Objects Reference (or for off-line browsing after downloading the zip archive).

ftp URLs are links that point to optional addons and/or latest bug fixes (see folder ending with ...addons+fixes) on our anonymous ftp server (ftp://ftp.sysecol.ethz.ch). These days depending on the browser you use the access to our ftp server may require a ftp client such as the excellent Fetch (Mac) or WinSCP (Windows) or any other ftp client available to you. Alternatively on a Mac, copy the provided ftp URL and use the Finder's menu command "Go -> Connect to Server...", paste the ftp URL contained in the clipboard, connect as a guest user, and enter your name if asked for a password (the latter conforms to the internet etiquette for anonymous ftp; should you insist on your privacy, feel free to do so by entering whatever you like). Note also that ftp – regardless how outdated it may appear these days – offers the advantage of letting you see and download the files with the original time stamps.

To unpack sea.bin archives under modern macOS we recommend to use the excellent utility The Unarchiver from the AppStore (Note, the free Stuffit Expander seems no longer able to extract its own archives). However, within the recommended Macintosh emulators (vMac, Basilisk II, Sheepshaver) the downloaded self-extracting archives (.sea) should work fine.

From this site you can download the following software packages (freeware - copyright authors and ETH Zurich):

Easy ModelWorks - MacOS, Windows
RAMSES - MacOS
Includes MacMETH, Dialog Machine, ModelWorks, ISIS, and RAMSES Auxiliary Library for Macintosh; but not RASS.

RAMSES Extras - MacOS
Some useful additions to RAMSES, like Alpha editor support (M2 mode) for Macintosh.

MacMETH - MacOS
A fast Modula-2 language system for the Macintosh.

DM, MW, and AuxLib for Windows - Windows
Includes Dialog Machine, ModelWorks, and RAMSES Auxiliary Library; but of course no MacMETH, and not RASS.

RASS - OS X, Solaris ( New!

updates and fixes)
Includes Dialog Machine, ModelWorks, ISIS, RAMSES Auxiliary Library and RAMSES Science Library.

The same software is also available from our no-frills Compact Download Table. It is particularly handy if you are only updating or are looking for some extra goodies such as the Alpha Editor Support we provide.

Important Notice for Macintosh Users

Our software runs on all Macintosh, including Intel Macs (latest tested Mac OS X 10.8.2, Intel). However, there are some caveats to keep in mind:

If you wish to do serious development work with our software and also wish to execute programs fully interactively, you face constraints. Though it is true, that you can still run our software on any Mac using the latest OS X, some of it, notably fully interactive Dialog Machine programs, require to emulate Classic, which may be tricky, since it is no longer officially supported by Apple (see below for hints on how to accomplish this).

Yet another variant is to use only the Batch Dialog Machine, i.e. to dispense with execution of fully interactive Dialog Machine programs, and be content with command line execution. RASS-OSX (see below) offers this. Since our approach to programing is orthogonal with respect to interactive vs. non-interactive use, this constrain is not crucial. You can still go anytime back to interactivity, should it become available again, or vice versa.

When you wish to have full interactivity, we still recommend then to use whenever possible Classic version MacOS 9.2.2 run within OS X version 10.4.11 (Tiger)! This is not only easy, but also works seamlessly. We have several such systems working flawlessly, e.g. our high-end simulation server cluster. Note, OS X version 10.4.11 (Tiger) is the last OS X from Apple still supporting a fully integrated working Classic allowing for AppleScript commands beeing exchanged between Classic and OS X. This platform works very well, in particular when the editor AlphaX is used with our software, and we give still full support for this platform. Note, however, this also requires your Macintosh is not Intel based, but a Power PC Mac such as a G5. A fast G5 should serve you still very well.

To the solution for Intel Macs involving emulation: If you have developed programs using our software, remember that your programs can all also be run in batch mode. Any Dialog Machine program made with RAMSES can also be made with RASS-OSX, which needs no Classic. You only need to recompile and the resulting programs should run on all Macintosh OS X computers including Intel based systems. We offer with RASS-OSX a full featured development system that runs under the latest OS X. Again we recommend to use AlphaX or AlphaCocoa and its M2 mode. Any such developed Dialog Machine program can then be ported back to Classic withouth any change and run there as well. Note also, that with the latest RASS-OSX you can create universal binary Dialog Machine programs. Such programs execute both on older PPC Macs as well as newest Intel based Macs.

To profit from all interactive features of our software, however, you still need Classic. If you wish to merely execute programs under OS X, this can be easily accomplished in a manner that is almost not noticable to the end-user of an Intel based OS X Mac. I do this for instance in my courses using a "Limits to Growth" world model. Here an overview of all options:

A Classic disk image ('Classic_Support.dmg.bin') is available here (hints on how to best use this disk image). It is recommended for use on Power PC Macs running OS X version 10.4.11 (Tiger).
On Intel Macs you can use Classic emulators (open-source, freeware). According to our tests our software runs fine under all of these emulators. Depending on the Classic MacOS you wish to use, use either Basilisk II or SheepShaver, or Mini vMac. We offer fully preconfigured and out of the box working solutions, i.e. disk images, for some of these emulators here (for copyright reasons access restricted to ETH Zurich members).
Mini vMac works also very well, seems to be rock solid and efficient. It is best suited to embed individual Classic programs you wish merely to use. E.g. I use this technique to offer CourseWare to my students. Since the RAMSES software is backward compatible to Mac OS 3.2, it is a piece of cake to use such programs with Mini vMac under Mac OS 6.0.8 (still available from Apple). Examples are "Limits to Growth" world model or Easy ModelWorks.
Here you find compact installation instructions for Basilisk II and our hints, might also help you to get going with Classic emulators. Here some of the more comprehensive Basilisk II emulator web sites I know of: Wikipedia, EMaculation.
Emaculation.com offers most useful information on emulation of the Macintosh in general.

To fully profit from the latest developments we also strongly urge you to upgrade to the latest versions of our software. Should you encounter problems, we recommend first to recompile all your code! To learn more on these issues visit README MacMETH and/or README RAMSES. Please, don't hesitate to contact us should you have more specific questions on compatibility issues or should you make experiences contrary to the ones described here. Thanks!

Here you can download Easy ModelWorks, a software that allows you to interactively model and simulate simple systems, and to explore the behavior of any coupled differential or difference equations in time and state space. Easy ModelWorks is the small sister of ModelWorks, that forms part of the large, advanced modeling and simulation package RAMSES.

Dialog Machine, ModelWorks, and Auxiliary Library for Windows

Here you can download the Dialog Machine, ModelWorks, and the RAMSES Auxiliary Library for Windows. All public interfaces are identical to the software as released for the Macintosh platform. Consequently you can develop for example the implementation of a dynamic model on a Macintosh and port it in source code form to an IBM PC or vice versa. You have only to make sure that you build your implementation by using only the interfaces and functionality of the Dialog Machine, ModelWorks, or the RAMSES Auxiliary Library. The resulting code should then be highly portable among all three supported platforms, i.e. Macintosh, IBM PC, and Unix. (Note, on the Macintosh platform the Dialog Machine, ModelWorks, and RAMSES Auxiliary Library form part of RAMSES and are released as one big package only).
