Hi, I am trying to measure the impedance of water medium. I have calculated impedance (given in the jpg) and made a table with varying frequency. The problems that I have encountered with my model (given in mph file) are,

  1. I could not measure the impedance (actually resistance) at 0 hz frequency. It is showing "Singular matrix. here are 24041 void equations (empty rows in matrix) for the variable comp1.V." this error. However, after removing the air medium around my water cylinder, the error was gone and gave the result at 0 hz. Why?

  2. Real part of impedance is becoming abnormal with the increase of frequency. why?

  3. Reactance part should be decreased with frequency. And also the value should be similar to my calculation. Am I using the wrong equation for impedance? (1/ec.Y22)

  4. I was trying to separate plot of "f vs impedance", "reactance vs resistance" and "f vs capacitance". but failed.

It would be great if someone helps me in this regard.

Thank you, Aftab
