For each part, two of its sides are orthogonal straight lines and other two are b-splines. The four parts were then meshed using 2nd order quadrangular meshes. The issue is that the element tags assigned by gmsh are not contiguous. An example of contiguous element tags can be seen in `contiguous.png` attachment, in which the element tags increments continuously along one row and then moves at the beginning of the next row.</div><div><br></div><div>We need a similar kind of contiguous element tagging in our non_contiguous.geo mesh.</div><div><br></div><div>I will be very grateful if you can give me some suggestions to create a mesh like the one shown in `non_contiguous.png` with contiguous element tags.</div><div><br></div><div>Note: The offset in the element tags shown in the plot have been removed, i.e., if the element tags assigned by gmsh starts with N and increments as N, N + 1, N + 2, ... , then in the plot it has been changed to 0, 1, 2 ... .</div></div><div><br></div><div>Thank You</div><span class="gmail-HOEnZb"><font color="#888888"><div>Aman Abhishek Tiwari</div><div>Department of Physics</div><div>IIT Kanpur, India</div><div><br></div></font></span></div></div></div></div></div></div></div></div></div></div></div></div></div></div></div></div>
