Hello Aswan,

Your geometry can be created by taking the difference between two cones (if your computational domain is the solid part of the needle), or by simply drawing a cone (if your computational domain is the space within the needle).

It sounds like you may be new to COMSOL Multiphysics so I'll offer some pointers on how to get up to speed with the software:

There are quite a number of resources you can draw upon to learn how to use COMSOL Multiphysics regardless of your specific application. I am mentioning here the main ones, in no specific order, and I should mention that this is not a complete list by any means. I hope it will prove useful to you nonetheless.

First, of course, there is the software's documentation. You can access it through the File > Help > Documentation menu or by browsing your COMSOL installation folder to the "doc" folder. The documentation includes both theory manuals and tutorial manuals. Many tutorial models are also available already set up inside the software via File > Application Libraries.

The COMSOL website also offers many video tutorials on a wide range of topics in the Video Gallery and worked-out models in the Application Gallery. You will also find longer archived webinars here. The COMSOL website also offer a Blog, in which many posts discuss how to simulate specific phenomena or using particular features of the software; they are highly technical and detailed.

COMSOL offers many instructor-led training courses.

Finally, and maybe most importantly, I strongly recommend the Learning Center videos to get a solid foundation for your modeling with COMSOL: they cover the entire process of setting up a model from start to finish, and are a great resource for self training.

Best regards,

Jeff
