help文件的翻译-- Zero out the initial... 是什么意思
ansys 13.0 版本的fluent中help文件下的--LES 求解策略中有段话不明白，还请大侠释疑如下：
Zero out the initial statistics using the solve/initialize/initflow-statistics text command, before restart solution, enable ...
1. zero out ... 是什么意思，也就是说用solve/initialize/ini.. 这个命令来干什么？
2. restart solution，怎么操作才算是 重新启动这个solution
先行谢过！！ 我把帮助文件贴出来，补充说明一下.
Zero out the initial statistics using the solve/initialize/init-flow-statistics text command. Before you restart the solution, enable Data Sampling for Time Statistics in the Run Calculation Task Page, as described in User Inputs for Time-Dependent Problems. With this option enabled, ANSYS FLUENT will gather data for time statistics while performing a large eddy simulation. You can set the Sampling Interval such that Data Sampling for Time Statistics can be performed at the specified frequency. When Data Sampling for Time Statistics is enabled, the statistics collected at each sampling interval can be postprocessed and you can then view both the mean and the root-mean-square (RMS) values in ANSYS FLUENT.
后来研究了一下，好像是将统计值置零的意思，但是我怎么没找到那个命令？
还有 Start by running a steady state flow simulation using a Reynolds-averaged turbulence model such as standard - , - , or even RSM. until the flow field is reasonably converged and then use the “solve/initialize/init-instantaneous-vel”text command to generate the instantaneous velocity field out of the steady-state RANS results.
双引号里面的那个solve/initialize ...那个命令也没有找到，怎样才能换模型呢继续计算呢。请教各位先知了，谢谢！ 自己调研了一下，原来这里面的两个操作步骤是通过输入命令来实现的，在fluent下面敲入响应的命令就可以了。至于效果如何，计算时间有点短，也没看出有什么用来。
