I am completely new in working with COMSOL Multiphysics. I am trying to draw a cylindrical shaped wire wound around the square block(as seen in the attached picture). The cylindrical wire is perfectly smooth at its sides and is following the Bézier curve generated before. But at the corners of the square it is not not following the Bézier curve previously drawn. I am using the 'sweep' action to sweep the curve using a work plane perpendicular to the actual work-plane the square block is in .
It would be of great help if you help me finding the error that I might be doing. It would help me to understand the section of building geometry in COMSOL Multiphysics better.
I cannot see the picture either. But I can imagine that if you have a sharp, 90 degrees corner, the program understands it as different segments.
Try rounding up the corners with a very small radius so that the model is still valid for your study.
Dear Rauhl,
The cad kernel cannot create a "real" sweep (a limitation of the NURBS I'm afraid). When you are sweeping using a spine curve the CAD kernel tries to adjust the resultant object but it can produce "funny" objects if you do not control the sweep. You can use the tolerance for that but I will probably chop the spine curve in different sections and use several sweeps rather than only one. You can chop the spine curve near the corners and perform the straight sweep, then you can sweep the last face of the sweep following the spine surrounding the corner and so one...
Kind regards,
Julian
