Your hint and the tutorial example was very useful!
I could make what I wanted to do.
Thanks Erik!

Thanks Erik!
OK, I’ll use the loader.
I have a basic scene in which I included a component defined by myself let say myComponent.
In the myComponent handle event “updateOnBeginStep” I have the following code:

   std::cout<<"MyComponent updateOnBeginStep!"<<std::endl;

which is working fine which means that I can handle the event, and sofa does not crash.

Now when I add :

   std::cout<<"MyComponent updateOnBeginStep!"<<std::endl;
   sofa::core::loader::MeshLoader *my_mesh;
   my_mesh->setFilename("/mesh_models/test_mesh.stl");
   sofa::helper::vector< Vector3 > my_vertices;
   my_vertices = my_mesh->getVertices ();

Sofa crashes at the setFilename line!

In the debug mode the heap is :

0	sofa::core::objectmodel::DDGNode::updateIfDirty	DDGNode.h	192	0x7ffff7b3ba8c	
1	sofa::core::objectmodel::Data<std::__cxx11::string>::beginEdit	Data.h	437	0x7ffff4726757	
2	sofa::core::objectmodel::DataFileName::setValue	DataFileName.h	91	0x7ffff6782d07	
3	sofa::core::loader::BaseLoader::setFilename	BaseLoader.h	117	0x7fff9fdd98c3	
4	sofa::component::controller::MyComponent<int>::updateOnBeginStep	MyComponent.cpp	167	0x7fff9fdeb62a	
5	sofa::component::controller::MyComponent<int>::handleEvent	MyComponent.cpp	115	0x7fff9fdeb0ab	

I hope that this description is clear? What should I do to load the file and access to its vertices?
