hfss assigning current excitation

Hi. This is my 1st post about hfss.
How to simulate a thin wire (cilinder), with a current running into it? I didnt find any documentation about Excitaton > Current. Please, help!

Hi! You should see Help-> Search-> current
As example:
Assigning Current Sources
Assign a current source when you want to define the magnitude and direction of the current flow through a surface. A current source is used when the feed structure is very small compared to the wavelength and the electric current on the surface is assumed to be constant across the feed points.
1. Select the object face to which you want to assign the current source.
2. Click HFSS>Excitations>Assign>Current.
The Current Source dialog box appears.
3. Type the source’s name in the Name text box or accept the default name
4. Type the value of the source, in volts or amps, in the Magnitude box. You can assign a variable as this value.
5. Specify the current flow direction by drawing a vector:
a. Select New Line from the Current Flow Direction pull-down list.
The Current Source dialog box disappears while you draw the vector.
b. Select the start point of the line in one of the following ways:
• Click the point.
• Type the point’s coordinates in the X, Y, and Z boxes.
c. Select the endpoint of the line using the mouse or the keyboard.
The endpoint defines the direction and length of the line.
The Current Source dialog box reappears.
6. Click OK.
When the source is selected, an arrow indicates the direction and a letter (v or i) indicates the type of source.
