Help Needed! Drawing a Half-Wave Sinusoid in Simulink

AI Thread Summary
To draw a half-wave sinusoid in Simulink using the equation I(t)=360sin(pi*t/0.4) for 0<=t<=0.4 and I(t)=0 for 0.4<t<=1, it's essential to use a Sine block with the correct amplitude and frequency settings. Users recommend adjusting the time step to increase the number of points for a smoother graph. The desired output color can be achieved by changing the block's properties. Ensuring the frequency is set to 7.85 is crucial for accurate representation. Following these adjustments should yield the correct half-wave sinusoid graph.

Dear all, I am pretty bad at Simulink and I want to draw out a half wave sinusoid with the equation:
I(t)=360sin(pi*t/0.4), 0<=t<=0.4
I(t)= 0 , 0.4<t<=1

Any help or suggestions?
I've tried using the Sine block with amp=360 and freq=7.85 but the graph looks weird.
I want to get the graph in blue but only managed to get the one in yellow.

You're not using enough points to generate the sine. Reduce the time step.

Thread 'Weird near-field phenomenon I get in my EM simulation'

I recently made a basic simulation of wire antennas and I am not sure if the near field in my simulation is modeled correctly. One of the things that worry me is the fact that sometimes I see in my simulation "movements" in the near field that seems to be faster than the speed of wave propagation I defined (the speed of light in the simulation). Specifically I see "nodes" of low amplitude in the E field that are quickly "emitted" from the antenna and then slow down as they approach the far...

Thread 'EMF (Electromagnetic Field) & EHS (Electromagnetic Hyper Sensitivity)'

Hello dear reader, a brief introduction: Some 4 years ago someone started developing health related issues, apparently due to exposure to RF & ELF related frequencies and/or fields (Magnetic). This is currently becoming known as EHS. (Electromagnetic hypersensitivity is a claimed sensitivity to electromagnetic fields, to which adverse symptoms are attributed.) She experiences a deep burning sensation throughout her entire body, leaving her in pain and exhausted after a pulse has occurred...
