<div>Dear all,</div><div><br></div><div>i'm new to Gmsh and i'm trying to mesh a simple rectangle with a wire attached to it, and then writing everything in a ".unv" file (i'm attaching both the .geo, .msh and .unv file). I have problems in performing some operations.</div>
<div><br></div><div>1) Is it possible to require that two opposite sides of the rectangle be meshed with the same nodes (apart a translation?). For example, side x=0 has nodes (0, y_n, 0), side x=a has nodes (a, y_n, 0). If, so, is it possible to require this for two opposite faces of a solid, e.g. side x=0 has nodes (0, y_n, z_m), side x=a has nodes (a, y_n, z_m)?</div>
<div><br></div><div>2) Also, is it possible to require a symmetric mesh with respect to a point, one or more lines, or one or more surfaces (on a symmetric object, of course)?</div><div><br></div><div>3) Is it possible to set different colors on different elements of the mesh? I need to use color A for all the 2-node lines, color B for all the triangles not touching side x=0 of the rectangle, color C for all the triangles touching side x=0 of the rectangle. In doing this, I have two problems:</div>
<div><br></div><div>3a) I cannot assign different colors to the different triangles, and </div><div>3b) I cannot save the colors of the elements in the ".unv" file. I get always a '7' in the place of the color for all the elements. I would need to change that number.</div>
<div><br></div><div>Sorry if some of the points are trivial, or too weird to have them implemented.</div><div><br></div><div><br></div><div>Thank you very much for the attention and congratulation for designing such a useful and easy-to-use software.</div>
