Thank you for your answer. Well, in this case I'm not only interested to analyze magnetic field. This is why I would like to simulate the Coil of the image. I would like to evaluate the behaviour of the coil acording to number of turns, diameter of the coil. Also I've been check some information about to terminal Coils. So, I would like to evaluate the differences that may occur generating variations in the coil design. 


Nevertheless, Ikept trying with the first design and I managed to perform the simulation. Then, I would try to evaluate the behaviour of two Coils. 

Now, I would like to Know what is about the problems that now appears in the Message Manager. Also I would like to know, how I can decrease the simulation time (In this case, the simulation of the image coils, lasted approximately 32 hours).
