一、安装认证服务器setupRlm32
二、然后拷贝文件rlm到C:\Program Files\Tecplot\RLM下覆盖原文件,首先用资源管理器停止这个应用rlm,然后再替换,即把文件rlm拷贝到C:\Program Files\Tecplot\RLM下
三、拷贝tecplotlm.lic文件到C:\Program Files\Tecplot\RLM下覆盖原文件
四:安装程序setup360_win32,选择安装路径,可装在C盘,也可更改在其他盘,点击change即可,选择安装功能OK,finish,安装完成五:在命令提示符cmd(开始-->运行-->cmd)中输入netsh winsock reset 六:然后运行C:\Program Files\Tecplot\RLM下的文件rlm,弹出对话框,自动运行,不要关(第六步是在地五步的基础上面安装成功的)六:运行程序Tecplot 360 2011,出现error点确定,弹出licensing对话框,选择Network License下的License Server Name栏目,在空白处填上localhost 已经可以使用了
五、重启电脑,完成安装(对于此程序,必须重启)。
我的版本号是:Tecplot.360.2011.R1.v13.1.0.15185-Lz0
首先说一下,我的安装包打开后包括setup360-win32.exe 和crack文件夹。
crack文件夹打开后有tecplotlm.lic ,rlm.exe ,SetupRlm32.exe ,可能还有个安装说明的txt文件。
安装步骤:1.安装crack文件夹中的SetupRlm32.exe。
2.把安装包中crack文件夹里的的所有东东复制到c:\Program Files\Tecplot\RLM
注意:可能提示rlm.exe无法删除,那么用360强力删除就可以了。
3.安装setup360-win32.exe,中间什么都不用输,不用管,直到安装完成。
4.运行c:\Program Files\Tecplot\RLM\rlm.exe,出现dos窗口,不要关,让它一直
运行。
5.打开Tecplot360 2011 程序,出现error提示框,点击ok,出现对话框。
选择Network License,License Server Name 填写上localhost,点击ok就可以
了!(License Server Name我随便写了一个,不是写的localhost,照样可以运
行哈。

Tecplot的使用入门与技巧汪继文前言Tecplot 是一种绘图视觉处理,使用Tecplot来驾驭您的资料会更显轻松无比,从简单的xy图到复杂的3d动态模拟,Tecplot可快捷地将大量的资料转成容易了解的图表及影象。
表现方式有等高线、3d流线、网格、向量、剖面、切片、阴影、上色等…Tecplot是一种资料视觉化软件,可以进行科学计算,将电脑计算后的资料进行视觉化处理,便于更形象化地分析一些科学数据,是一种传达分析结果功能最强大的视觉化软件。
Tecplot可以用来建立一个图形,二维数据的等高线和矢量图块。
使用Tecplot可以很容易地在一页上建立图形和图块或者对它们进行定位。
每一个图形都是在一个文本框中,而这些框架可以被复制再修改,这就会使你很容易地对一个数据集显示其不同的视图。
本文主要对Tecplot的使用做一个简单的说明,先简单介绍一下各菜单及其选项的一些基本而主要的功能,然后说明一下边框工具栏的基本用法,最后会分别就几个一维和二维图形来说明一下Tecplot中一些常用的概念和一些基本图形的处理方法。
