some elements are not being meshed

Hello;
Can anyone tell me why yellow element is not being meshed? The pic is attached.
Thank you.

Sometimes the meshing scheme needs to be explicitly set. In this case, the volume might be swept from the front surface to the back. You can set the source and target surfaces in the Mesh-Volume-Mesh-Sweep panel.

The brownish volume looks like it might be taller than the bluish volume. Is that correct? Could you share this model so I can look at it closer?

Hello;
Sorry for the late response. I waited for a response for a while and somehow I have missed your comment. I uploaded the file but it says the size of file is too large since it is 3.3 MB. Is there another way to send you the file.??

I’m not sure why you couldn’t upload it. You can send it to support@csimsoft.com.
