Memory management when concatenating arrays [message #92185]

I have a large multi-dimensional array that is split across several files by time.

i.e. file1 contains the first 1000 timesteps, [360,180,1000], file2 contains the next 1000 timesteps [360,180,1000], etc.

What I want to end up with is one big array that's read say all 10 files in and is (360, 180, 10000).

What I'm doing is this in a loop:

all_data=[[[all_data]], [[data]]]

But I quickly run out of memory trying to concatenate in this way.

I tried using temporary

all_data=[[[temporary(all_data)]], [[data]]]

but this doesn't help.

Is there an efficient way of doing this?

Cheers
