Installation

Download

There is no public download link for MORe. If you are interested in a copy, please go to https://www.more-simulations.ch .

Prerequisites

MORe depends on following python packages: scipy, numpy, pysparse, traits, traitsui, weakref, mayavi, matplotlib, chaco, enable, os, glob, shutil, subprocess, zipfile, tempfile, base64, json, hdf5storage, uuid, pyface, itertools, sympy, logging, time, gc, pdb, numbers

Following tools are called through command line and, thus, have to be installed on the system: 7zip (Windows only)

MORe uses finite element models from ANSYS Mechanical. Therefore a working installation of ANSYS Mechanical is required (ANSYS version 16 or later). The required license is

• for mechanical-only use of MORe: ANSYS Mechanical Pro and for
• thermo-mechanical use of MORe: ANSYS Mechanical Enterprise.

Restrictions on ANSYS models:

• shell elements are not supported for thermo-mechanical simulations
• lumped inertia is not supported for thermo-mechanical simulations

For the optional MATLAB toolbox and Simulink library, MATLAB and Simulink are required (MATLAB version 2017b or later).

Recommended Installation of Prerequisites on Windows OS

Installation of MORe

1. Install Enthought EDM for Windows 64 bit for your account (run as user and not as administrator)
2. If your company uses a proxy server, add the user environment variables HTTP_PROXY and HTTPS_PROXY with the address of the proxy server as value [1]
3. Download and unzip MORe
4. Run the installation script MORe/src/python/install_more.bat (run as user and not as administrator)
5. Copy the startup scripts MORe.bat and spyder_MORe.bat from MORe/src/python/startup to a location of choice (e.g. Desktop)

Installation of the ANSYS MORe Interface

1. Copy the folder MORe/src/ansys to a location of choice on your computer
2. Add the folder MORe/src/ansys to the user environment variable ANSYS_MACROLIB [1]

Installation of the MATLAB MORe Toolbox

1. Install the MORe MATLAB toolbox by running MORe/src/matlab/MORe.mltbx using MATLAB
2. Type open more_library in MATLAB, wait for the library to be opened and save the library (in order to have the library version congruent with the MATLAB version)
3. Install 7zip and add the program path (usually C:/Program Files/7-Zip) to the environment variable PATH [1]

Update to a newer version

1. Download and unzip the new version of MORe
2. Run the installation script MORe/src/python/install_more.bat
3. Replace the old MORe/src/ansys by the new one
4. Install the MORe MATLAB toolbox by running MORe/src/matlab/MORe.mltbx using MATLAB
5. Type open more_library in MATLAB, wait for the library to be opened and save the library (in order to have the library version congruent with the MATLAB version)

Recommended Development Environment (IDE)

As IDE, Spyder is installed. Following configuration is recommended:

1. Start Spyder by running spyder_MORe.bat
2. Set Tools->Preferences->IPython console->Graphics->Graphics backend to Qt4 (or Qt)

(1, 2, 3) To edit environment variables in Windows, click on Windows start button and search for “Edit environment variables for your account” (for an English installation of Windows) or run the command “%windir%system32rundll32.exe sysdm.cpl,EditEnvironmentVariables” (win + r). If the environment variable does not exist, create a new one. For multiple entries, separate with semicolon and without whitespace.
