Help required for simulation in HFSS

[Abhishekabs]

hi friends I have designed patch antennas directional coupler in HFSS
when i start simulation it always give me error for "mesh"
When I solved examples from tutorials of HFSS it was not giving error.
I followed the same standard procedure for patch anenna design * simulation.

I have simulated it
The proble was with software(HFSS 10)
