It is a great piece of software and it has proved to be extremely useful to me.<o:p></o:p></p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal>However, I have found that if I have two closed bodies that share a common face, the 2D surface mesher will mesh that face twice and I will end up with duplicate triangles on that face. I have tried playing with all the options available to me but I cannot seem to stop this behaviour. Are there any plans to correct this in later versions? This is particularly important as often in CEM you will need a meshed face that separates regions of differing material properties and duplicate or overlapping triangles are not allowed.<o:p></o:p></p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal>I have attached a small diagram to help explain my problem.<o:p></o:p></p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal>Thanks in advance<o:p></o:p></p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal>Best regards,<o:p></o:p></p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal>David<o:p></o:p></p></div></body></html>
