TIDAL - 水体模拟软件

TIDAL是模块化的软件包，适用于水资源管理，城市和工业规划，城市和工业废物处置和管理，环境影响，污染管理和遵守等实际问题。TIDAL软件包模拟了大型水体如海湾，河口，河流，湖泊和沿海水域的流体动力学和水质行为。它融合了很多物理过程对水体的影响；这些包括电流，潮汐，风，重力和科里奥利力，测深，摩擦，源和汇，以及化学反应。TIDAL还规定了沿海低地的动态淹水和排水。

用户界面是通过会话FREEFORM语言提供的英语的命令语法，并允许程序的命令行执行。 FREEFORM也是其他ACRi软件使用的通用语言。

TIDAL一些软件特点：

• 瞬态和稳态模拟

• 复杂水深和不规则海岸线

TIDAL可在FORTRAN编译器的计算平台上使用。这些包括所有Windows，LINUX和UNIX平台。

【英文介绍】

TIDAL software package simulates the hydrodynamics and water quality behavior of large scale water bodies such as bays, estuaries, rivers, lakes and coastal waters. It incorporates the effects of a number of important physical processes on the water body; these include currents, tides, winds, gravitational and coriolis forces, bathymetry, friction, sources and sinks, and chemical reactions.

TIDAL also provides for dynamic flooding and draining of coastal lowlands.

It is a highly modular program which has been applied to a wide range of practical problems in water resource management, urban and industrial planning, disposal and management of urban and industrial wastes, environmental impact and, pollution management and compliance.

The user interface is through the conversational FREEFORM language which provides for simple English-like command syntax and allows command-line execution of the program. FREEFORM is a common language used by other ACRi software as well. Please see ANSWER Examples site to see the simple yet extremely effective way of programming thru English language. Although there are no certain plans, it is anticipated that TIDAL will be in the list of applications supported by CFDStudio environment.

TIDAL is available on any computing platform that supports a FORTRAN compiler. These include all Windows, LINUX and UNIX platforms.

During the past 25 years, TIDAL has evolved from a simple mathematica model for flow and heat transfer into a comprehensive Computational Fluid Dynamics software tool for analysis of a wide range of problems. it provides for coupled transport of fluid, heat and multiple chemical species in complex three-dimensional geometry. It is able to simulate the transient or steady state behavior of laminar or turbulent flow in compressible or incompressible fluids with chemical reactions, conbuter code with few modules and fewer options to a software package with almost 1000 modules and a versatile set of options that can accommodate almost any user requirements.

TIDAL has been used to analyze problems as diverse as low pressure film deposition, cooling of electronic components, automobile fluid dynamics, ventilation of tunnels, HVAC design optimization, analysis of process tanks, design of ramjects and aircraft enginess, and missile launch tube simulations, lubrication of bearings, and performance of high Mach number missiles. 

In the process, TIDAL has evolved with the user's needs. At every stage, the flexibility and generality of the software were maintained while options were added to address user requirements. As a result, today TIDAL provides a flexible format that is bound neither to a specifi algorithm, nor to a particular methodology. Rather, it provides a framework that facillitates experimentation. The user can change numerical schemes, solution method. matrix inversion algorithms, or any of the physical or mathematical features.

Of all features of TIDAL , two deserve special mentio: generality of applications over a diverse range of problems, and ease of use provises by the conversational FREEFORM command language. These have enabled TIDAL to emerge as a leading software in its field of application.
