memory requirement - std::bad_alloc (2 replies)

Hello,


I am using PALABOS for simulating single fluid in porous media in 3D. I have a large dataset with 100 000 000 lattices.

I was not able to run this dataset. I received the following error:

terminate called after throwing an instance of 'std::bad_alloc'
what(): std::bad_alloc
Aborted (core dumped)

What are possible reasons for this error? How to solve it?

Do you know how to determine necessary memory before running simulation?


Thank you very much.
