Import multiple ply files

[Karltlbm]

Hello all,

I am trying to import a mesh file containing multiple cylinders. It comes from a .ply file transofmed into a .mesh using PyMesh.

Using the simplest import code

load "msh3"

string meshFileName = "file.mesh";
mesh3 Mesh = readmesh3(meshFileName);

I get this error and FreeFem crashes. Any ideas ?

Error GenericElement::Read1 3 17104 : -1 -1 -1 , -1

Thank you for your time.
