Running TUFLOW

Introduction

TUFLOW is a standalone console application. As such, it doesn't require installation to run. The standard TUFLOW setup steps are listed below.

• Free DEMO and Tutorial Version of TUFLOW:

1. Download the latest TUFLOW executable from the Tuflow website: Tuflow Release Download
2. Download the TUFLOW Tutorial and Demo models: Tutorial Model Download
3. Run TUFLOW using any of the options listed below. User documentation for the tutorial models is available from the Tutorial Model section of the Wiki.

• Licensed Version of TUFLOW:

1. Download the latest TUFLOW executable from the Tuflow website: Tuflow Release Download
2. Download and install the Licensing Dongle Drivers: Installing Licensing Software
3. Run TUFLOW using any of the options listed below.

Executable Management Advice

Save a copy of the downloaded TUFLOW executable files to a dedicated location (eg. C:\TUFLOW\Releases\)

A TUFLOW release consists of two different versions of the executable as follows:

1. TUFLOW_iSP_w64.exe - Single Precision Windows 64-bit
2. TUFLOW_iDP_w64.exe - Double Precision Windows 64-bit

Refer to the TUFLOW Executable Section of the TUFLOW manual for advice when best to use the different TUFLOW versions. Each version of TUFLOW also has four TUFLOW .dll files and several system .dll files included in the download. Do not delete or relocate these dlls. All .exe and .dll files must be placed in the same folder and kept together at all times.

When replacing TUFLOW with a new build, we recommend archiving the past .exe and .dll files by creating a folder of the same name as the Build ID (e.g. 2013-12-AA-iSP-w64), and placing all files in this folder. Build ID information is appears in the top bar of the Console window when TUFLOW is executed, and is reported in the header of the .tlf file.

Run Options

Single Simulation Execution

There are a number of ways TUFLOW can be started, in each case the TUFLOW executable is started with the TUFLOW control file (.tcf) as the input. There are a number of optional switches that can be used to control advanced features as outlined in the TUFLOW manual.

Common ways of initialising a TUFLOW simulation are:

• Using a Batch-file
• Running TUFLOW from UltraEdit
• Run TUFLOW through the command window
• Running TUFLOW from Notepad++
• Textpad Instructions Including Running TUFLOW (Provided by CHM2Hill / Halcrow)
• Running TUFLOW from Windows Explorer (Pre-Windows 7)
• From QGIS with the TUFLOW QGIS Plugin
• From ArcMap with the ArcTUFLOW Toolbox
• For miTools users, please see the miTools manual for instructions.

Multiple Simulation Management

• Using a Batch-file
• TUFLOW Run Interface Manager (TRIM)
• For miTools users, please see the miTools manual for instructions.

Scheduling Simulations

• Using Task Scheduler

Cloud Computing

Use of the Cloud is an excellent option where large volumes of simulations (eg. Monte Carlo runs) are to be completed within a short timeframe. There is no limit to the number of simulations that can be run in parallel!

Three options are available. click the links below for :

1. Organisation Cloud Software Execution
   Organisations with access to Cloud hardware may host Network Licences within their own Cloud domain.
2. TUFLOW Cloud Simulation Service
   Let BMT help you manage your TUFLOW simulation execution on the cloud. This service is designed for bulk simulation of any TUFLOW product (Classic, HPC or FV). As such, it is typically used for design event modelling that requires 100’s to 1000’s of simulations of a pre-built, stable model. This service is less suited to model build activities which often require regular modeller/model interactions. We recommend model build activities be completed using a standard client licence as it is typically a more cost effective option.
   
   • Licences are scaled to meet your project demand (i.e. this is independent of any in-house licences you may own).
   • The BMT service offers flexibility regarding the Microsoft Azure Cloud hardware available for your project. We tailor the hardware and storage resource specification to suit your project requirements (based on project size, model size and also the simulation type).
   • This service has no limitations in terms of hardware type. We offer simulation on both CPU and GPU virtual machines.
