 Posted: Fri Apr 19, 2013 2:13 pm Post subject: Out of memory problem |
 |
|
Dear all,
I am running a big code for flow simulation and when I am using a mesh with large number of nodes, FORTRAN 90 gave me an error F6773 cannot allocate array out of memory
So how I handle this error and if I use FTN95 the problem will be solved or not.
Regards

A bit more information might help answer the question...
How many nodes and how big is the array that you're trying to create, for a start... |

it about 10000 nodes and I have many arrays in the code , the biggest one dimension is (5*number of nodes ,5*number of nodes)

| 5*10000 x 5*10000 is 2.5*10^9 elements. That's a lot of memory. Assuming single precision, that's 10 billion bytes. I'm not too surprised that it ran out of memory... |
