CST Simulation Error Help

Dear all,

I'm designing a feeder network (Planar transmission line network) to feed antenna elements in CST Microwave studio. The frequency being used is 1.7-2.1GHz (3G). I have tried for 8 lines/wavelenght, 15 lines and 20 lines per wavelength but failed to get the results. When I start simulating the design, I'm getting following error (s):

Unable to generate MESH
mesh is too dense or calculation domain may have zero volume.

Please can anybody help me come out this problem asap!

Thanks,

post your model and I will model it.
