Convergence Level in S4L
-
Hi,
I have recently downloaded Sim4Life V2 and ran the MRI Low Pass Coil simulation from the tutorial. I noticed that the convergence level in the simulation setup of the tutorial is set to Medium (-50 dB), but the convergence level only reaches -15 dB. However, my B1+ distribution and Admittance plot matches those shown in the tutorial manual. Does this mean the solution did not converge? I appreciate your response. -
A simulation can end in a couple different cases: If the specified level of convergence is reached, or if the specified number of periods are simulated. In the case of that tutorial, the simulation is set to run for 15 periods, and so it ended before a -50 dB convergence was reached. Convergence is a spectrum, and the level of convergence required for a given application is up to the user's discretion.
