I have to simulate a ideal transmission line and I have drawn the following schematic in LTSpice IV.
When I run the command to simulate it works but only show a 10V steady value on the output in both start and end of transmission line. I'd like to see the transient values. Can anyone point me what I have done wrong?

You have used a fixed voltage source, which will have 10v output at t=0. LTSpice uses this to initialise the line and capacitor, then the simulation runs.
You need to use a source that starts at zero, then transitions to 10v a little after t=0. A PWL source will do, or the simpler pulse generator.
