I am trying to convert the unstructured mesh generated in ICEM into OpenFOAM and while converting the mesh using utility fluent3DMeshToFoam i got the following error.One thing i want to add the size of fluent.msh is 409.1 MB.The error is
Dimension of grid: 3

PointGroup: 6 start: 0 end: 1306894. Reading points...done.

new cannot satisfy memory request.
This does not necessarily mean you have run out of virtual memory.
It could be due to a stack violation caused by e.g. bad use of pointers or an out of date shared library
Will anybody help and i am waiting.
Thanks In Advance.

What is your memory peak during running the tool with this mesh?
"Cannot find bounding box for zero sized pointField, returning zero"
first thoughtid you export any empty field, faces from ICEM? You can simply check this by viewing the .msh-file in an text editor (even if this is VERY unusual).
second thought: reduce your meshdensities by ... 10 times, export, try the mesh-tool. Just to make sure the error is size-related.
