[运算]问一个cst cpu并行的问题

多谢回复！ 3eV(2  
可是我最多只能仿到1600万网格左右的模型 `3$S^|v  
再大了就说内存不足了 =%:mZ@x'
 
而内存也没用多少 od- 0wJN-m  
我机器的内存是32G的 $?OuY*ZeY9  
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) +98~OInySZ

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. wmY6&^?uS

How to increase windows resources - desktop heap memory (important for many models opened and DC-postprocessing) (Faq #283) ? Z8_(e0U

RXgi>Hz  
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. qX:54$t

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. LPT5d 7K@

The Desktop Heap memory is defined and can be increased in the registry editor in the following place: HI']{2p2}t  
p=9G)VO  
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Session Manager\SubSystems -> Windows ~z>2`^Z"

In this long string the Desktop heap memory is defined under: "SharedSection=1024,3072,512" (third value is not always present). "v jFL9

On a 32bit system we recommend to change the SharedSection values into:   SharedSection=1024,4096,2048 SLz^Wg

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 G,M &z>ub0

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
