Need Technical Help Answered
Hi,
I am new in Onscale. Currently I am doing Piezoelectric Transducer Simulation. I just followed a tutorial.In the tutorial, they used 50000 Hz frequency and got a very good result. But I used a low frequency. like 2000Hz. In this case, my model failed to estimate the result. It shows this problem:
Here is the link of the tutorial which I followed:

My problem is, how can I simulate Piezoelectric Transducer in low frequency?
Thank you.

Hi Abdul,
You can check the generated 'filename-estimate.flxprt' file for the error message. My guess is that you haven't increased the mesh for the lower frequency so the mesh is likely too coarse and some parts are not being realised anymore, this can cause loading issues etc, but the flxprt file will tell you exactly where the error is occuring.

Hi Chole,
I can't open .flxprt file. Can you please give me another suggestion. Its really very important for me.
Here I used wavelength based mesh configuration and 1000 elements per wavelength.
Hi Abdul,
What do you mean by you cannot open the flxprt file? Have you downloaded it from the cloud? 1000 elements per wavelength will be an extremely large model. We recommend using 15 elements per wavelength as a guideline but this may need to increase for lower frequency models.
Meshing is fundamental to accurate results in FEA, for more info have a look at our meshing blog series:
Part 1 - https://onscale.com/blog/meshing-in-fea-introduction-to-meshing/
Part 2 - https://onscale.com/blog/meshing-in-fea-meshing-considerations/

I Can't estimate my model. How can I download a file from cloud?
If your model is failing the estimate, a flxprt file will be generated in the same directory of the file you are estimating.
