Memory allocation

hello,

I have question regarding optistruct memory allocation.

For a simple analysis I allocate 1500 MB for the analysis. But when I check the output file optistruct selects Current Memory : 150 MB. 

 

What could be the reason for this? Does optistruct choose required memory from allocated memory and send the rest memory out of core?

The picture showing the situation is also attached. 

 

Thanks in advance.

    I think when you 'allocate' 1500MB memory, Optistruct solvers understands that's the MAX limit of memory. So if your model is not so big the real used memory will be smaller that allocated value.
