you are wondering what is the relation between a Showerhead and FEA Analysis ?
The form of the oscillation depends mainly on the system which is behind that. Here you can think that the determinant factor to get quickly the temperature you want is the speed of your water boiler and your water installation (but I am not a specialist in that…).
If you have done some automation, you may also see in all that the regulation process of your system through integrators, derivators, etc… but this is another story… I have to keep something left ;-)
Transient analysis is not only valid for temperature, but also for any kind of mechanical event. You can think of a shock or an impact for example. When an object is touching the ground, it is submitted to a material wave of energy, which may destroy it (or not). Pretty cool, huh ?
Now you can go back to the dictionary’s definition and see if it makes sense now (I hope it will ;-) )
In FEA Analysis, Transient Analysis is to put inside the dynamic type of Analysis. because it is an event depending on time (obviously).
You have Direct Transient Analysis, Modal Analysis, Explicit Transient Analysis (the funniest type ;-) )
Continue to follow me to understand more about all these analyses :-)
