Issue with fix ttm/grid

I am trying to simulate radiation damage behavior where I am depositing both electron and lattice temperature in the structure. I’m simulating in the super computer. But I always have the out of memory error. I tried simulating 100x100x1, 50x50x1, 10x10x1 electron grids, they all give the same errors. The simulation box is 30nmx30nmx45nm. Can anyone help me resolve it? I’m attaching my job script description too.

There is not enough information here to give any meaningful advice.

How do you know the issue is with fix ttm/grid?

I’m primarily using ttm/grid because in the manual it says that ttm should be used for small electronic mesh.

That does not answer my question.
