periodic

Could you please anyone help me to input Direct Cyclic Periodic Pressure Load.

I have a sine load of amplitude 50 kPa and frequency 5 Hz (ang. freq 31.42 rad/s).

I need to ramp my load to 100 kPa for 5 seconds and then to run the sine load of above amplitude with its mean load on 100 kPa. The sine load go for 10 seconds.

I try with Direct cyclic periodic pressure, but when I check the pressure on applied surface, the pressure not seems what I am applying.
