I am trying to model a transformer using two spiral inductors on two separate chips. This setup is commonly used for magnetic resonance coupling to send data between two substrates. I want to eventually export the results into a spice simulation; however, I am getting some execution errors when I try to simulate the setup.
I get:
[info] Simulation completed with execution error on server: Local Machine. (2:42 PM Mar 22, 2007)
[error] Initial mesh, process mesh3d : Unable to recover all the surface triangles. Additional information may be available in the "model_analysis.html" file in the project results directory.
Now, I imagine you would usually get this due to not enough mesh points or even due to discontinuities on surfaces that are supposed to be united or touching, however I cannot find any such problems with my model.
A note: The reason why I am using inductors of so many turns is because Q is not important in the coupled resonators. The magnitude of L is most important since you need adequate coupling between the two inductors. Furthermore, since the data is typically sent by inducing short current pulses in a positive or negative direction across the tx inductor, high Q inductors are prone to oscillatory behavior.
Can some one please help me out here!!
