    Question about pout

    Hi. I do my simulation and want to get data from results.   I use command 'calc-pres' and set simulation area 45 mm x 110 mm and box size is  0.1e-3 and simtime is 1e-3 But when I use 'pout-hist pr...

    Hi. Chloe. That's what I'm asking you. In Acoustics, beam focus must place in front of geometric focus. Maximum pressure must place before 63 mm but you said focal point is 63.  You and I did simul...

    Hi Chloe I can get result looks like correct. But when I find maximum data position, that is not 63 mm. The maximum value place on 64.5 mm Is maximum pressure place at 63 mm in data?

    Problem of beam focus point

    Hi.  I have problem of beam focus point. As I ask before, I'm in trouble of prove modeling and result. I designed concave transducer and fire sine wave, 200kHz, 1 pulse with 1 MPa  (sine 0.2e6 1e6 ...

    Question about box

    Hi. I'm still simulation about point source. Here is my modeling My question is signal at focal point depends on box size. Let's assume I set box as 0.1e-3, Then I can get 1 MPa at focal point. Bu...

    Hi,   Actually I have no experimental results because it's very difficult to measure real data. Goal of this simulation is to predict power of source.   I think there is minimum size of source. Whe...

    I'm just gonna paste my code. The output signal change depend on source size. Please help..   -------- mp omp 32 symb x1 = 0.0symb x2 = $x1 + 5.e-3symb x3 = $x2 + 19.e-3symb x4 = $x3 + 41.e-3symb x...

    How can I make point source?

    Hi. I'm trying to make point source with 1MPa, 200kHz.Half sine. pupple : point source (waternl_1) blue : water (waternl, it's same waternl_1) green : air I'm trying to drive function at surface o...
