Hyunjae Songさんが投稿を作成しました: 回答済みProblem of wave propagation direction
Hi. I design two medium and propagate wave medium 1 to 2 I don't know how I can fix it. Can I set boundary condition between two medium? (both medium is water now) I already set absr 4 boundary c...

Hyunjae Songさんが投稿を作成しました: 回答済み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...

Hyunjae Songさんがコメントを作成しました: 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...

Hyunjae Songさんがコメントを作成しました: 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?

Hyunjae Songさんが投稿を作成しました: 回答済み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 ...

Hyunjae Songさんが投稿を作成しました: 回答済み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...

Hyunjae Songさんがコメントを作成しました: 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...
