I'm a MTech student, new to CST.
I'm working on a microstrip antenna, to be fabricated on curved(cylindrical) structure. So, I intend to develop a palnar patch on a flexible laminate and mount it on the cylinder.
Now to study the effects of curvatures, I will be running the simulation for cylinder of different radii.
Now the problems I'm facing is that, very often I'm encountered with these warning messages.
1. (Some No) mesh cells are represented in staircase mode and filled with PEC.
2. The calcluation seems to be unstable. Reduce time step/ PBA limit.
3. The mode at inhomogenoes port is hybrid. Reduce port size
Can anybody help me to explain the reasons and implications of these errors on the simulation results and how I can avoid them.
Your help will be of invaluable help.
