如何实现自动export每个timestep的结果（ ANSYS CFD-POST, pulsatile flow）
2018-03-16 02:47阅读：
用CFX做出求解文件后，有时得出的.trn文件名是不连续的，还有一种情况是连续但没有逻辑。
例如设定了300 time steps,
为3个周期，后处理时只需要最后一个周期的results.
1）第一种情况是得到了320.trn
到478.trn，中间不连续（自己的case，不赘述）
2）第二种情况是得到了244.trn到
342.trn，共99个文件，最后一个343.trn没有单独的trn文件，但在CFD-POST界面里会出现。虽然这种情况是连续的，但是其实的244.trn按照timestep的规律应该是201.trn.
所以，这就为自动输出每一个timestep的结果带来了困难，因为不能保证每次求解完初始timestep生成trn文件的名称。
# Load a transient file and read the time step list
> load filename=myFile.res
!$timestepList = getValue('DATA READER', 'Timestep List');
!@timesteps = split(/, /, $timestepList );
! foreach $ts ( @timesteps ) {
> load timestep=$ts
…operations you want

在使用session功能生成.cse
file之后，可以将以上代码整合进去，实现每一个timestep结果文件的自动输出。Hope
it helps.
My case example:
# Session file started: 2018/03/15 16:49:59
# CFX-15.0.7 build 2014.04.26-07.00-131803
# To avoid unnecessary file pre-processing and modifications,
include
# COMMAND FILE at the top of your session file.
# If it is not included, the file is assumed to be older and
will be
# modified for backward compatibility.
COMMAND FILE:
CFX Post Version = 15.0
END
