Hi,

I am trying to simulate the Bfield and E field induced by two loop coils. I am defining them numerically and in the coil geometry analysis step, I get this error for my second coil which is the mirror of the first one. The model with one coil works well but when I add a second coil, it gives me this message:

*Segregated Step 1 Attempt to evaluate negative power of zero. - Function: ^ Failed to evaluate temporary symbolic derivative variable. - Variable: comp1.mf.coil2.ccc1.normg@VDN$2comp1.mf.coil2.ccc1.pYm.internal - Defined as: ((-exp((-i)phase))(2comp1.mf.coil2.ccc1.gY))(((((comp1.mf.coil2.ccc1.gX^2)+(comp1.mf.coil2.ccc1.gY^2))+(comp1.mf.coil2.ccc1.gZ^2))^(-0.5))0.5) Failed to evaluate temporary symbolic derivative variable. - Variable: comp1.mf.coil2.ccc1.weak1@VDN$2{test@2}@VDN$2comp1.mf.coil2.ccc1.pYm.internal Failed to evaluate expression. - Expression: (-(((((-exp((-i)phase))(2comp1.mf.coil2.ccc1.gY))(((((comp1.mf.coil2.ccc1.gX^2)+(comp1.mf.coil2.ccc1.gY^2))+(comp1.mf.coil2.ccc1.gZ^2))^(-0.5))0.5))comp1.mf.coil2.ccc1.Vdom)((-comp1.mf.coil2.intmtcd(eps+comp1.mf.coil2.ccc1.normg))/((eps+(comp1.mf.coil2.ccc1.normgcomp1.mf.coil2.ccc1.Vdom))^2))))dvol Failed to evaluate Jacobian of expression. - Expression: (comp1.mf.coil2.ccc1.S-(comp1.mf.coil2.intmtcd(eps+comp1.mf.coil2.ccc1.normg)/(eps+(comp1.mf.coil2.ccc1.normgcomp1.mf.coil2.ccc1.Vdom))))dvol Failed to evaluate Jacobian of expression. - Expression: (comp1.mf.coil2.ccc1.weak1)(dvol)**

I understand that I must have a variable that becomes 0 to a negative power but I don't understand what the variables comp1.mf.coil2.ccc1.gX, comp1.mf.coil2.ccc1.gY or comp1.mf.coil2.ccc1.gZ might represent.

Thanks in advance for your help
