In the script obtained from the link for IV characteristics analysis, I am not able to calculate the required results for the gate voltages and drain source voltages below

**# Gate-source voltages**

gate_source_voltages = numpy.linspace(-1.0, 1.0, 41)*Volt

**# Drain-source voltages**

drain_source_voltages = numpy.linspace(-0.05, 0.05, 11)*Volt

But, it worked quite well when I calculated for two drain-source voltages, set as

**# Gate-source voltages**

gate_source_voltages = numpy.linspace(-1.0, 1.0, 41)*Volt

**# Drain-source voltages**

drain_source_voltages = numpy.linspace(-0.05, 0.05, 2)*Volt

I have attached my input script for your perusal.
