Hi ,
i read this discussion:

viewtopic.php?f=4&t=3809&p=13226&hilit=Transient+wave&sid=66796dd4df9c8272815bfc9c701e74d6#p13226

for the solvers method should i follow him or not:

Code: Select all
Solver 1

Linear System Solver = "Direct"
Linear System Direct Method = Umfpack
Steady State Convergence Tolerance = 1e-09
End

For the momment i suspect this part is wrong:

Code: Select all
Variable Coordinate 1, Coordinate 2, Time;  Real  MATC "if (tx(0)==0.4375&tx(1)==-0.15)sin(2*pi*20000*tx(2))*(tx(2)<=0.00005);else 0;"

Hi,

I intended to reply to your question whether or not you should use the settings proposed in the discussion you referred to in the previous post.
I don't know why your result is not what you expect. I don't have the time (and the mechanics knowledge) to check the physics of your problem and to verify if what you entered in the sif file really corresponds to what you think you have entered...
So I'm afraid you will have to check for yourself - the line of code you show seems to be a 20 kHz oscillation, is that correct?

Hi,

this part of your MATC expression seems strange to me:

Code: Select all
sin(2*pi*20000*tx(2))*(tx(2)<=0.00005)


What if you included the (tx(2)<=0.00005) in the if() condition?
I would play with the MATC expression to see if it changes something...

HTH,

Matthias
