General Questions and Answers / geometric constraint

« on: May 20, 2011, 11:01 »

Sir,
i've a two probe system with 36(left electrode)+(18+32+18)-central Region + 36(right electrode)
i want to constraint the electrode as well as electrod element in scattering region(as recommended in tutorials). i tried with
 geometric_constraints = range(0,53)+range(86,139)
it shows error ------ saying indices can't be more than 68.
--------------------------
tell me if my syntax is right or wrong ??
--------------------------

and one more thing is the indexing order same how they appear in script ?
--------------------------
Thank you.
