Method for partially fine grid Answered

Hi.

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.

Thanks.

    Hi there, 

    You have to do this in Analyst Mode, you cannot do this in Designer yet. Here is an example of a 2D PZT plate in water in which I have meshed the pzt plate finer in the thickness than the water: https://onscaleus.sharepoint.com/:u:/s/External/EVBqrDQLtN9CjmA4xEN2pRIBBV_n8pkg4FlH8Y1JMdRhnQ?e=qAKzuW

    Thank you for your help

    Can I ask one more things?

    I want to zoom at contact position between finer grid and coarse grid.

    I used zoom command but I don't know how it moves position.

    You can only use zoom using standard graphics. Here is some example code:

    grph

          type stnd

          plot matr

          zoom 2

          pan u 0.1

         end

     

    This code will plot your materials in standard graphics, zoom in so the image is twice as close and shifts the image 10% upwards.
