Hi,<br><br>Could anyone tell me the degrees of 'Bspline' and 'Spline' on Gmsh?<br><br>I just learned how to approximate a circle with Bezier curves:<br>http://www.tinaja.com/glib/ellipse4.pdf<br><br>Could we do the same thing with 'Bspline' on Gmsh?<br>(Yes, I'm aware of 'Circle' and 'Ellipse' on Gmsh.)<br><br>Apparently, the following 'Bspline' does not look like a circle...<br><br>//-----<br>Point ( 5) = { 0.0000, 1.0000, 0.0000};<br>Point ( 6) = { 0.0000, 0.0000, 0.0000};<br>Point ( 7) = { 1.0000, 0.0000, 0.0000};<br>Point ( 8) = { 0.0000, 1.0000, 0.0000};<br>Point ( 9) = { 0.5518, 1.0000, 0.0000};<br>Point (10) = { 1.0000, 0.5518, 0.0000};<br>Point (11) = { 1.0000, 0.0000, 0.0000};<br><br>Circle (102) = {5,6,7};<br>Ellipse (103) = {5,6,7,7};<br>BSpline (104) = {8,9,10,11};<br><br>Physical Line (202) = {102};<br>Physical Line (203) = {103};<br>Physical Line (204) = {104};<br>//-----<br><br>Regards,<br>Shin<br> </div></body>
