Hi Himal, the vertices of your coarse mesh must be located on the geometry provided by the IGES file.
It is hard to tell from that amount of information where exactly your error comes from. I advise you to draw a sketch of both your IGES cylinder and your coarse mesh. Usually you should find out this way what the error message is about. On a different note: Creating a cylinder out of a cuboid is general not a good idea, as your cells near the corner vertices get distorted. I would rather advise you to choose a coarse cylinder from our GridGenerator namespace <https://www.dealii.org/current/doxygen/deal.II/namespaceGridGenerator.html#a5cdda7b4a76d509af7d1a8dc1320ddb0> instead.
