窗口/对话框消失解决办法
很多用户在操作Simpack Pre前处理或Wizard导航界面时，经常会把模型树（或其它窗口）拖到界面以外，而无法找回该窗口；求解器设置窗口由于界面大，也会经常被拖动到屏幕以外，而无法关闭或者打开。这个问题通过重启电脑、重启Simpack软件、甚至卸载重新安装Simpack软件也无法解决，给用户带来很大的困扰。通过删除软件配置路径下的Simpack配置.ini文件而解决。删除该.ini文件后，启动Simpack会自动重新配置并生成新的.ini文件。
Simpack每个版本对应一个.ini文件。
Windows操作系统中，该.ini文件位于%APPDATA%\SIMPACK\simpack-<xxxxxx>.iniLinux操作系统中，该.ini文件位于$HOME/.config/SIMPACK/simpack-<xxxxxx>.ini该.ini文件在Windows操作系统下的位置可以参考下面的路径：C:\Users\lma2\AppData\Roaming\SIMPACK文件夹中，如下图所示。
注意：删除该.ini配置文件前，以防意外，请先备份该文件。在Simpack帮助文档中，对该配置文件有详细的介绍。
Usually the .ini file is specific to the Simpack major and feature release and located in the user-specific configuration directory, which is %APPDATA%\SIMPACK\simpack-<xxxxxx>.ini on Windows and $HOME/.config/SIMPACK/simpack-<xxxxxx>.ini on Linux. Note that <xxxxxx> must be replaced by the six digit Simpack release number; for example, 202100 for release 2021 and all related maintenance releases. The x releases use a 1 instead of a 0 for the sixth digit; for example, 2020x has the release number202001.This .ini file is written by Simpack when the user explicitly changes a setting and also when the user interface is closed.The .ini file contents are not officially documented and may change between different major and feature releases. The file should not be edited by the user.Maintenance releases (with a third digit in the release number) do not have their own .ini files, they use the according major and feature release .ini file.The .xml files located in the user specific configuration directory contain settings which Simpack automatically updates. You should not modify or remove these .xml files.Note also that when a new Simpack major and feature release is started for the first time then Simpack searches for the .ini files of the highest feature release that has been used by the user. If such an .ini file is found then the contents that are still applicable are used to create the new .ini file. This mechanism ensures that settings from earlier Simpack releases are automatically adopted and do not have to be specified again.
