Chg_mem error problem with MCNP

[zhangxm]

TL;DR

Hi,
I have a problem with MCNP. The problem is : the input file can run correctly on WindowsXP system,but when I run it on a more powerful computer with win10 system , the MCNP showed "chg_mem error". How to solve this problem?

No !
perhaps you have a very old version of MCNP (4 ?)

The version is MCNPX 2.5 and MCNP5. I use the input file of human voxel phantom to calculate organ dose, it can run correctly on an older computer with winXP system , which run very slowly due to the poor ability of the cpu . So I transfer it to a more powful computer with intel Core i9 cpu and win10 system, then i run it with the MCNPX 2.5 and MCNP5 respectively which were installed correctly on the above computer, but the result showed chg_mem error. What's the reason ?

can you give your input file ?
I can try with mcnp and mcnp6 with windows 10,

thanks you a lot. can you give me your email address? so i can give you the input file.
or you can email me to the address: amms_zhangxm@163.com

I found if the number of voxels is lower, for example 1500000, the input file can run correctly on the win10 system, but if the voxel number is bigger, for example above 19000000, it will show the chg_mem error

I have the same problem with Win 10! how can I resolve it?
thanks!
