Simulation Combiner Channel Parameters
-
Hello,
What voltage values should I input as the amplitudes under Analysis->Simulation Combiner->Channel Parameters if I want to visualize the E-field for a simulation with boundary settings set to a constant flux? Here are the pertinent details and what I've already tried.
I am performing an LF-electro ohmic quasi-static simulation with the rhesus macaque (Miss Able) model. I created two electrodes with cylinders to resemble the screw electrodes that we use for epidural ACS in my lab.
Under the Simulation->Boundary Conditions->Boundary Settings for the two electrodes, I set the Boundary Type to Flux, with a constant flux of 2.47 mA. Then, I checked the Treat as Port box.
I understand that the voltages for the amplitudes under Analysis->Simulation Combiner->Channel Parameters applies to the analysis, so it did not change the constant flux value that I input for the simulation stage. However, I don't know what voltages I should input to reflect the true E-field value for the 2.47 mA.
I tried acquiring the appropriate voltages for the simulation combiner amplitudes by outputting the EM potential for each of the electrodes. This yielded a max of 0.707 V. Then, I input that value into the simulation combiner amplitudes field, setting amplitude 1 to 0.707 V and amplitude 2 to -0.707 V. Next, I clicked on EM Sensor Combiner for the overall field, EM E, and Slice Viewer. However, when I tried following these same steps for a constant flux of 1.98 mA, it also exhibited 0.707 V.
So, either I'm doing something wrong or I do not understand the parameters that I am using to visualize the E-field properly. I was also wondering if perhaps the electric field was normalized for the simulation combiner, so it is not giving me the true E-field value for a given constant flux. Could you please help me output the accurate E-field value for ACS, given a constant flux of some value (in milliamps)?
Thanks,
Ian
