Hi

Is it possible to create a line source in 2D?
I want this line source to send a sine wave pressure pulse.

P=100sin(wt).
By study is time dependent but i want to specify the frequency .

How can i model this?
Its quite urgent.


Thanks a lot for your time and effort!!

Regards
Glenston

Hi

To answer my own question.
Choose the pressure boundary condition in your physics.

So for a 2D structure it becomes a line and specify the the pressure in the p0 edit field.
