[vtkusers] unable to allocate 178MB for an array

I am trying to extract surface of a goemetry and write it into a STL. I use

vtkSmartPointer<vtkDataSetSurfaceFilter> dsf =

But I am getting this error in vtkOutputWindow:

vtkIdTypeArray (00C30690): Unable to allocate 46656437 elements of size 4

This is about 187MB memory; however, I can not allocate this amount of
memory on
a 12GB RAM. I believe that I must be able to allocate this chunk of memory
but for some reason it does not go through. I tried to delete every other
arrays in my program to make sure that there are not any hidden consumption
of RAM but that didnot help.

I will be grateful if anyone has any idea how to fix this.

Many thanks!
