Optistruct错误信息与解决方法？
从业挺久，还是会遇到一些奇怪的问题。
问题描述1：
A fatal error has occurred during computations:
*** INTERNAL PROGRAMMING ERROR # 8014 ***
Data block name: ir0tbr. Reduced length is longer than original.
* DATAMANAGER ERROR in subroutine "datams".
这个问题出现在优化分析中，模态频响分析类型
怎么解决的1：
这个错误在寻找时，不会同时遇到下面这个错误。
*** ERROR # 1829 ***
DRESP1 card 3 uses a function in the ATTB field. For responses used
in modal frequency response optimization, simple functions cannot be
used in the ATTB field when the number of modes on the EIGRL card
is not explicitly specified.
最终确定的解决方法：
FREQ1 1 10.0 0.2 1990
$FREQ3 1 10.0 2000.0 LOG 20 2.0
显而易见FREQ3是无法确定分析频率数量的，这个在做模态频响分析类型的优化时不能这样设置。
问题2
NOTE # 1405
Memory is being expanded from 19406 MB to 21351 MB.
Estimated working storage was not enough for inserting the data block
"iedatatmp" (26 MB + 5 MB)
In order that we may improve our memory estimates, it would be appreciated
if you could email this information and your run command to Local Altair
support in your region. If it is possible, please also include input data.
这个问题出现在优化分析中，直接不去迭代计算了。。绝对不是内存或者存储的问题。
怎么解决的2：
计算的太太慢了，难道是变量很多？没关系吧，以前也有更大的模型也算挺多，现在迭代一步就要超过5小时？？？
这是一个问题。
问题3
*** ERROR # 1898 ***
Approximated constraint 44 does not match with response 43548 at the
first iteration.
Approximated constraint = 4.9017184735e-03
Approximated response = 4.9017236845e-03.
*** INTERNAL PROGRAMMING ERROR ***
in file "conapp.F", at location # 5763.
ioerr(1) = 1898
**** ABORTING RUN DUE TO AN INTERNAL ERROR ****
怎么解决的3：
重启动，重新提交试试吧。
