Hello,
I am attempting to run some simulations with the ISFET tutorial but I would like to change the dimensions of the isfet to be more similar to modern devices. Does anyone have some experience with this? I cannot seem to find all the parameters that need to be changed to run a succesful simulation.

Hello Jakub,
Are you speaking of this tutorial model? If so, note that it comes with a pdf document containing step-by-step instructions that cover, among other things, how to set up the geometry.
Note that, in general, changing the geometry of a model may imply that other changes need to be made throughout the model for it to continue giving accurate results, particularly as far as the mesh and solver settings go. Sometimes the physics may be different too! Think for instance of how a flow can go from laminar to turbulent at different scales. So it's always a good idea to inspect the entire model after you make your changes.
I'll take the opportunity to highlight below some of my favorite training resources for new users of the software.
Best,
Jeff
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, mostly online but also in person again.
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.
