Method for partially fine grid Answered
I have problem of making mesh.
I have to model 2 block, which has 10 um and 20 mm.
As you can see, there is a huge difference with them.
Center frequency is 100kHz and box size is 150, then mesh size is 100 um.
In this case, I think it's wrong simulation bcz 1st block is much smaller than mesh size.
So, I want to make more mesh only in 1st block.
How can I do that?
Please help me.
I did make larger box size, but it need too much time.
