Computations in COMSOL Multiphysics can potentially be memory intensive. However, buying more memory than you can address from a single process is not worthwhile for COMSOL Multiphysics in 32-bit mode. Thus, more than 2 GB (or 3 GB with the switch) on Windows and 4 GB on Linux/UNIX cannot be utilized by the 32-bit versions of COMSOL Multiphysics. When buying a computer, check that the motherboard supports the amount of memory that you require and that additional memory modules are not excessively priced.
On 32-bit Windows platforms, memory fragmentation can be a problem. This means that you may get an out-of-memory error even though you apparently have available memory left. The reason is that no contiguous memory block is available. Once again, should you encounter out-of-memory problems, we strongly recommend that you migrate to a 64-bit system (see above).
关于内存问题,经常遇到空余内存较多,但是comsol提示out of memory,只是因为32位的系统对内存有限制,并且还有内存碎片的问题,虽然系统仍有空余内存,但是没有一个连续的大块供软件调用,就提示内存不足。
解决方法: 换64位系统是最好的办法! |
