Dear GetFEM++ Users,
I have an "invalid pointer" error in building a 1D mesh immersed in a 3D domain. I have no problem on my office's computer (i7 with Ubuntu12.04, GetFem-4.3) but just on my own laptop (i5 with Ubuntu14.04, GetFem-4.3).
I tried with a very simple mesh made by one segment that I discretize with 50 elements. The error occurs when I add the second point of the second element.
The code is the following (I added some control print because I am not able in debugging):
/// Read an arc from pts file and write to lpoints
std::vector<base_node> lpoints;
// build lpoints ...
#ifdef __VERBOSE__
cout << " Found an arc with " << lpoints.size() << " points." << endl;
#endif
/// Insert the arc into the 1D mesh
for (size_type i=0; i<lpoints.size()-1; ++i ) {
cout << "for i=" << i << endl;
// We need a couple of global indexes
// Points in the pts file are: begin, end, point, point, ...
size_type ii = (i==0) ? 0 : i+1;
size_type jj;
if (ii == lpoints.size()-1) jj = 1;
else if (ii == 0) jj = 2;
else jj = ii+1;
cout << " ii=" << ii << " jj=" << jj << endl;
cout << " p" << ii << "="<< lpoints[ii]
<< " p" << jj << "="<< lpoints[jj] << endl;
std::vector<size_type> ind;
ind.push_back(mh1D.add_point(lpoints[ii]));
cout << " ind" << ii << "="<< ind[0] << endl;
ind.push_back(mh1D.add_point(lpoints[jj]));
cout << " ind" << jj << "="<< ind[1] << endl;
//std::string MESH_TYPE1 = "GT_PK(1," + poly_deg + ")";
size_type cv = mh1D.add_convex(bgeot::geometric_trans_descriptor(MESH_TYPE), ind.begin());
I tried also:
//size_type cv = mh1D.add_segment_by_points(lpoints[ii], lpoints[jj]);
and/or:
//ind.clear();
} /* end of for loop */
but the error doesn't change. The output is the following:
Importing the 1D mesh for the vessel ...

p2=[10.78, 1.168, 1.052] p3=[10.56, 1.336, 1.104]

Do you have any suggestion?
Thank you in advance,
