Dear all,
I try to build a flow simulation using a domain simulation definition from an STL file (complex boundaries) with a free surface.
To do so, I try to mix two example codes, the first one from “aneurysm” for the STL side and the second, the “damBreak3d” for the free surface aspect.
As I’m at the beginning, I start to take part of the code located in the aneurysm.cpp file and go step by step. 
I can read the STL file and print some information of the readed file.
I try then to go to the next step which is transform the surface geometry to a TriangleBoundary3D structure. I add the following lines:
DEFscaledMesh* defmesh = new DEFscaledMesh(*triangleSet,resolution,referenceDirection,margin,(plint)0);
TriangleBoundary3D boundary(*defmesh);
delete defmesh;
boundary.getMesh().inflate();
Fisrt, when I compile with this new lines, I get lots of warnings (but no errors). When I try to run the simulation, it take all the 6 Gb of RAM and finish to crash with following :
terminate called after throwing an instance of ‘std::bad_alloc’
what(): std::bad_alloc

How to resolve this.
Thanks.
