I remember running the example without problem several months ago. Is it possible that some of the changes (adding BaseSolver, Pbd solver, etc.) influenced the calling of some functions in PBD? <i><span style='color:red'>testLineMesh</span></i>() also have this problem.<o:p></o:p></span></p><p class=MsoNormal><span style='font-size:12.0pt;font-family:"Microsoft YaHei UI",sans-serif'><o:p> </o:p></span></p></div></body></html>
