我还是怀疑软件和64位系统的兼容问题

How much memory does the transient solver need? (Faq #137) Z]aK'

As a rule of thumb you can expect that a model with 5 - 8 million (5e6 to 8e6) mesh points will require 2 GB of RAM. The exact memory requirement depends on many factors like volume and surface losses, dispersive materials, open boundaries, number of monitors, etc. 4Ay`rG

How to increase windows resources - desktop heap memory (important for many models opened and DC-postprocessing) (Faq #283) eN]>l

The windows operating system has a known limitation in the so-called desktop heap memory, which e.g. allows only a certain number of opened windows application. This can be a limitation in the number of CST models, which can be simultaneously opened on one PC. QlRoe|{  
X<Th{kM2  
Also when activating the option "DC-Postprocessing on the solver server", which is available under windows since 2006B-SP2, an increase of the default desktop heap memory is recommended.  M<Wn]}7!  
XYb^Cs;  
The Desktop Heap memory is defined and can be increased in the registry editor in the following place: RrO0uadmn  
G !1~i*P$u  
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Session Manager\SubSystems -> Windows $W/+nmb)@K  
{C/L5cZ]J  
This key "Windows" contains a very long string, which should be similar to the following lines 'wz\tT^  
`*" H/Q
G  
%SystemRoot%\system32\csrss.exe xI@$aTGq  
ObjectDirectory=\Windows $h 08Z

In this long string the Desktop heap memory is defined under: "SharedSection=1024,3072,512" (third value is not always present). vnC<*k4&v  
C(V[wvL  
On a 32bit system we recommend to change the SharedSection values into:   SharedSection=1024,4096,2048 p<=(GY-

On a 64bit system we recommend to change the SharedSection values into:   SharedSection=2048,20480,2048 >~5lYD

This applies to all variants of Windows NT versions 3.1, 3.5, 3.51, 4.0, Windows 2000, XP, 2003, Vista and Windows 7. ^"O{o8l>2

请问楼上hefang，在哪里查看CPU/GPU multithreading设置了多少。刚接触CST，不熟悉，多谢了

1600万网格大概只需要2G左右的内存就可以了，你的机器是32GB的理应不会出现这个问题 {%2vGn  
F}GPZ=T;  
对于CST MWS-T来说，仿真1000万网格大概需要1GB的内存，这个关系在网格数目越多则线性度越好

收到，非常感谢hefang管理员，祝天天开心
