Agenda • Why: Purpose/Goals/Objectives of this Focussed Theme – Develop ‘national’ CAE software – Enhance expertise in the use of commercial software packages • What: Tentative specifications of the developing CAE software packages 5

Why: Purpose, Goals and Objectives • Purpose: Thailand have capabilities to develop and effectively use CAE software • Goals: – Thailand have ‘national’ 3D CAE software used in ‘certain’ sectors – Thailand have sufficient human resource for CAE software developers and ‘advanced’ users • Objectives: – Develop 3D CAE Software for general engineering problems – Get people (developers & users) involved in this Focussed Theme 6

‘Certain’ Sectors Companies which cannot afford to buy CAE software Companies which can afford to buy Those who Those who CAE software know it is don’t know useful it is useful Use iCAE  Have expertise and/or Get more profit  Decide to buy commerical (or not) 7

Get Software Developers Involved • Research staff in research institutes • University academics & students • Research staff in companies ? • Freelances ? 8

MIKE 11 From Wikipedia, the free encyclopedia MIKE 11 is a computer program that simulates flow and water level, water quality and sediment transport in rivers, flood plains, irrigation canals, reservoirs and other inland water bodies. MIKE 11 is a 1-dimensional river model. It was developed by DHI Water • Environment • Health . MIKE11 has long been known as a software tool with advanced interface facilities. Since the beginning MIKE11 was operated through an efficient interactive menu system with systematic layouts and sequencing of menus. It is within than framework where the latest ‘Classic’ version of MIKE 11 – version 3.20 was developed. The new generation of MIKE11 combines the features and experiences from the MIKE 11 ‘Classic’ period, with the powerful Windows based user interface including graphical editing facilities and improved computational speed gained by the full utilization of 32-bit technology. 14
