Equivalent Bulk calculation error

[renren123123]

In calculation of device based on ZGNR with 180 atoms in scattering region, a following  error appears no matter the bias set is SZP or SZ, please help me! thanks a lot!

Answered many times already. You don't have enough memory for the calculation. Since the equivalent bulk can use more than the device calculation, you can try turning equivalent bulk off by choosing NeutralAtoms under "Device algorithm parameters".

Thanks! But we changed the paramter as above, and the same time, try to change SZP to SZ, by calculation on Dell computer with 32G internal memory, but the error remains! May be other problems? The ATK version is windows 11.8.2 . Thank you very much!

Such old versions of ATK are not supported anymore.
