This model is working well before some obstruction height is raise 0.5m.
After that it keeps showing this error at t=35s. the attach is the source
code and task manager when this error occurs. Please advice.

After setting RESTART=.FALSE., the input file works on my laptop. However, I am 
using a newer version. Try the case again with FDS 5.1.6. How much memory does your

machine have? I think that the message indicates that you do not have enough.

Hi Mc, My machine have 3GB of RAM. The model could be run until 35sec. After that the
error only occurs. I'll try the later version.

It appears that you do not have enough memory (RAM) to run this case. I suggest you

try the parallel version. How much RAM do you have?

Ran this on one of my PCs with 3 Gb of RAM with the 2GB boot option enableed (limits

RAM reserved for the OS) After startup Task Manager showed it was using ~1.2 Gb of

RAM.  At ~25 s it died with the memory error.

On my Linux machine, I've run beyond 25 s. The job is using 1465 MB VIRT -- which I

assume is virtual memory. This is 66% of the RAM. I looked at the .out file and 
noticed alot of Lagrangian particles. The first thing I would do is get rid of them.

The job is still running past 40 s, and the memory is still increasing as more 
particles are added. I'm going to stop the case. Run without particles and tell us

if the case finishes.

it could run till 900s.

I assume that this solves the problem.
