Hello respectable members

I am getting errors, while I am running this simulation of the conformal antenna, it is difficult to make coaxial probe layers of dielectric, pec pin when the antenna ground and substrate is a curvature, also my substrate is very thin 0.795 mm required for this design , so the cylinder I always create for the coaxial dielectric layer, it gets intersects with the substrate and patch surface of the curved surface. Therefore I cut one side of the probe dielectric cylinder layer. But there is always an error in my simulation ?  Can anybody please fix the error ? my probe pin diameter is 5mm that's the requirement for the design. .CST Studio Suite2023antenna
