URGENT!!! HFSS help

I am a new user in HFSS. I would like to simulate inductive coupling between two inductances. But the program gives me errors:

[error] Adaptive solution setup, process hf3d error: Matrix solver exception: out of memory.. (10:22:56 mai 17, 2010)
[error] Unable to create child process: hf3d. (10:22:56 mai 17, 2010)
[error] Simulation completed with execution error on server: Local Machine. (10:22:56 mai 17, 2010)

I think the problem comes from meshing. But I could not find the solution to reduce the tetrahedra. I have also uploaded the HFSS file. can you help me on that?

Thanks in advance
