Dear Neil,

You actually answered my question: there is no need for sensors, because node volateges can be examined (plotted) directly. The reason I asked is, because in another software probes must be placed to be able to see voltage. Now everything is clear. Tx for the kind help once again.

Andras,

I do not understand exactly what you want. The sensors are optional -- you can examine any voltages without adding a voltage sensor.Maybe you should describe the ideal behavior you want. Are these nodes reused in other components?

Maybe show a simple example that highlights the desired or unwanted behavior.

Regards,

Neil

Andras,

The problem with your model is that you have a TableCurrent that is hooked up only on one side and a voltage sensor that is only connected on one side. The other side must reference a voltage (such as ground).

I added a ground and this model builds (although you could equally connect to the existing ground although the wires become messy).

As to your second question, you should change the tableCurrent to a CombiTable and a current source. CombiTable can load from various files (including ASCII and .Mat) you can easily change your .xls format into a compatible file. See the Help for the file details.

The model would look like this:

Neil
