<div dir="ltr">Dear GMSH Team,<div><br></div><div>This is to bring to your notice following observations. I am using GMSH 2.12.0 and the geo file is attached.</div><div><br></div><div>1. Creating surface by rotate does not accept 2*pi [rad]. It just ignores. I would advise to mention if there is any limitation on angle to be used in "extrude by rotation".</div><div><br></div><div>2. The surface does created by rotation seems to be a bit strange [looking at iso lines]. Please refer to the image attahed.</div><div><br></div><div>3. When rotation angle is specified pi [rad], one of the edges get turned upside down. You may try by changing the value pi/2 to pi in the attached geo file.</div><div><br></div><div>Please see if there is any issue with this version! </div><div><br></div><div>Regards,</div><div>Amod</div><div><br></div><div><br><div><div><div class="gmail_signature" data-smartmail="gmail_signature"><div dir="ltr"><br><div>-----+-----+-----+-----+-----+-----+-----+-----+-----+-----+-----</div><div><b>Twitter:</b> @AmodK78, <b>Web:</b> <a href="http://www.cfdyna.com" target="_blank">www.cfdyna.com</a></div><div><b>LinkedIn:</b> <a href="https://www.linkedin.com/in/amod-kumar-4722375" target="_blank">https://www.linkedin.com/in/amod-kumar-4722375</a></div></div></div></div>
