Hi everyone,
I have just created a .lib and .olb file of a flyback transformer using the Magnetics Part Editor which is available with orcad (see View attachment trafo4042.zip).
As next step I have made a schematic using this transformer in order to test if it works properly (see ).
I have run a simulation in time domain but the following errors occured, which I cannot understand :
*Analysis directives:
.TRAN 0 1000ns 0
.OPTIONS DIGINITSTATE= 0
.PROBE V(alias(*)) I(alias(*)) W(alias(*)) D(alias(*)) NOISE(alias(*))
.INC "..\SCHEMATIC1.net"

Please does anyone have an idea why these errors occur?
For your information:
The pins of the transformer are set to "Passive".
