  • Ticket #160 – Description

    initial v2  
    1 Lone vertices (points not associated with any triangles) continue to cause minor problems such as the one attached. This ticket suggests exploring whether general_mesh can remove lone vertices upon creation.
     1When running \anuga_work\production\onslow_2006/test_export_results.py
     2there is the following error;
