<DIV><FONT size=5>Dear gmsh,</FONT></DIV>
<DIV><FONT size=5>I am a gmsh user in China.I just try to learn FEM by it.Now I just meet two problems in using gmsh.</FONT></DIV>
<DIV><FONT size=5>One is about physical entities.The pdf document says,"The purpose of physical entities is to assemble elementary entities into larger, possibly overlapping groups, <STRONG>and to control the orientation of the elements in these groups</STRONG>.If physical entities are defined, <STRONG>the output mesh only contains those elements that belong to physical entities.</STRONG> "This is useful,but I can't make it.The orientation(the sequence of the node's num ) is the same before and after I define some phisical entities.So is the output mesh which contains all the meshing elements I defined-physical or not.Would you please show me how to use physical entities effectively,maybe give me an example?</FONT></DIV>
<DIV><FONT size=5>The other is about <STRONG>Transfinite&Elliptic algorithm</STRONG>.Would you please give me a brief introduction about these two algorithm?</FONT></DIV>
<DIV><FONT size=5>I would appreciate if you reply.</FONT></DIV>
