Microfluidic channel simulation

I want to simulate my microfluidic channel model. Anyone who can assist me in detailed procedure? Anyone who can help in managing time dependent study and solvers?

Hello Lara,

There are plenty of models of flow in microfluidic channels in the Application Gallery, see for instance this link. For additional training materials to get going with the COMSOL software, see also the resources below.

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.

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.

Thank you so much, Jeff Hiller, for your valuable response. I truly appreciate your help. However, I am unable to find a tutorial specifically for microfluidic channels with multiple inlets. Most available tutorials focus on fluid flow in pipes, micromixers, diffusion separators, or micropumps.

I am currently simulating a model that is for bioanalyte detection, but I am unsure if I am setting it up correctly. Additionally, I am struggling to determine the time it takes for water to enter the inlet and fill the reservoir in COMSOL. I am also interested in analyzing the pressure difference between the inlet and outlet, but I am not sure how to check for this in the software.

Sorry for asking so many questions. I am a beginner and still learning. I would be truly grateful for any guidance.
