发布日期: 2016年2月3日

本次更新修复了 COMSOL Multiphysics 5.2、 COMSOL Server,以及 COMSOL 客户端中的几个小问题,并改善了其稳定性。更新为累加性质,也就是说,它同时适用于 5.1 版本及 5.1 更新 1,并包含了之前更新 1 中的所有更新。内容:* 更新了 COMSOL Multiphysics * 更新了 COMSOL Server * 更新了 COMSOL 客户端 * 更新细节(见另一个标签页)

更新 COMSOL Multiphysics

1

检查您的版本号

请确定您运行的是 COMSOL 5.2.0.166 或更高版本。在帮助菜单中,点击 关于 COMSOL Multiphysics 以检查您的版本号。安装更新前,请务必关闭所有 COMSOL® 会话

2

下载更新

在某些浏览器中,例如 Internet Explorer,下载完成后将弹出一个对话框,您可以直接在其中点击运行。 点击运行前,务必保证已关闭所有 COMSOL 会话。在其他一些浏览器中,例如 Chrome,您需要选择并运行已下载的文件,请参照下方的步骤 3。

安装

继续安装之前,请务必退出所有正在运行的 COMSOL 进程

Windows

运行所下载的 .exe 文件,将 COMSOL 5.2 更新解压到软件安装目录,例如 C:\Program Files\COMSOL\COMSOL52\Multiphysics

Linux

将下载的 .tar.gz 文件复制到 COMSOL 5.2 安装目录:cp comsol_5.2.0.220_linux.tar.gz [installdir]其中 [installdir] 为安装的根目录,例如,/usr/local/comsol52/multiphysics。通过命令解压缩:

cd [installdir]
tar xvzf comsol_5.2.0.220_linux.tar.gz

Macintosh

双击 downloaded .dmg 文件,加载磁盘镜像。在 Finder 中,打开已挂载的磁盘,然后双击 COMSOL 安装图标。选择 COMSOL 安装文件夹,通常为 COMSOL52/Multiphysics

4

检查您的安装

  1. 启动 COMSOL Multiphysics。
  2. 帮助 菜单中,点击 关于 COMSOL Multiphysics
  3. 确认当前版本号为 5.2.0.220(如果版本号不对,则更新安装未成功)。

更新 COMSOL Server

1

检查您的版本号

请确定您所运行的是 COMSOL 5.2.0.166 或更高版本。在文本编辑器中打开 [installdir]/uninstall/fl.ver,检查您的版本。安装更新前,请务必关闭所有 COMSOL® 会话

如果您已将 COMSOL Server 安装为一项服务,请确保此服务已停止。您可以按照以下步骤停止 COMSOL 服务:

  • 开始菜单找到 服务对话框:控制面板 > 系统和安全 > 管理工具 > 服务
  • 右击 COMSOL Service,选择停止
2

下载更新

在某些浏览器中,例如 Internet Explorer,下载完成后将弹出一个对话框,您可以直接在其中点击运行。 点击运行前,务必保证已关闭所有 COMSOL 会话。在其他一些浏览器中,例如 Chrome,您需要选择并运行已下载的文件,请参照下方的步骤 3。

4

检查您的安装

在文本编辑器中打开 [installdir]/uninstall/fl.ver,确保内容如下:

ver.build=220
ver.major=0
ver.name=COMSOL 5.2

5

启动 COMSOL 服务(仅适用于 Windows®

如果您已将 COMSOL Server 安装为一项 Windows® 服务,请务必在安装完成后启动此服务。您可以按照以下步骤启动 COMSOL 服务:

  • 开始菜单找到服务 对话框:控制面板 > 系统和安全 > 管理工具 > 服务。
  • 右击 COMSOL Service,选择启动

更新 COMSOL 客户端

如希望将 COMSOL客户端升级至 5.2.0.220 版本,请先卸载 COMSOL 客户端,然后在 cn.comsol.com/client-download/5.2.0.220 页面下载最新版本并重新安装。

您安装的 COMSOL 客户端版本应与所连接的 COMSOL Server 版本相同。
