There seems to be a memory problem.
OS: Win vista
Total Physical RAM: 4GB
MAybe windows problem not sure..
INPUT SUMMARY
Expansion order: 3
Number of partitioning levels: 9
Overall permittivity factor: 1
Total number of panels: 143580
Number of conductor panels: 143580
Number of dielectric interface panels: 0
Number of thin conductor on dielectric interface panels: 0
Number of conductors: 2
No expansions at level 9 (lowest)
fastcap: out of memory in file `C:\Documenti\Codice\FastSolvers\FastCap330_051224\fastcap\direct.c' at line 96
(NULL pointer on 128 byte request)
Total Memory Allocated: 1928600 kilobytes (brk = 0x42b050)
It's raining MEMS |

I changed the title of the topic since the problem you are experiencing looks like a real out of memory issue, not a memory leak.
FastCap2 informs you that it has already allocated 1.926 Giga of memory and that an additional request to the OS (we don't know of how much memory) has been refused.
So Windows has not allowed FastCap2 to allocate more memory, even if you have 4G physical ram. This probably means that your other applications, including Windows, were already using all other memory, including the swap. Please note that, since we don't know how much additional memory was requested, we don't know at which limit the request was refused.
You can maybe verify the situation using the Windows 'Performance' panel, or a more specific application like the Process Viewer (distributed as a tool with MS Visual Studio)
Best Regards,
Enrico

I get a similar error message running several problems i calculate. (Windows XP, 4GB physical memory)
Is there any solution to the described situation? I wonder why the program fails to get enough memory as there is "much" free memory left (little less than 1G). And if i reduce the complexity of the problem only slightly the program doesnt crash.
Thanks

To allocate a matrix in the source field,there is a limit memory. Try to meth the structure with smaller number of panels.

Windows uses a virtual address space of 4 GB, with 2 GB allocated to user-mode processes. User allocation can be increased to 3GB using the \3GB switch in boot.ini.

You can try using FasterCap. It has a smaller memory footprint, and is able to use a smart out-of-core algoritm to overcome the physical RAM memory limit
