Hi @jominkyung

Yes you can solve your nonlinear diffusion equation in FVTool, but you need to iterate. I have written a blog post about it previously:

Thank you for your quick reply.
I cannot grasp the code in your post because there are so many unknown functions.
Is there any other posts about the topic? I want to study more.
And can FVTool solve the nolinear PDE systems also?

Unfortunately, The post on nonlinear diffusion is done with Julia and JFVM.jl (which is a clone of FVTool. I'll add the matlab code when I find free time. You can go through my blog: http://fvt.simulkade.com for more examples.
You can also solve nonlinear PDE systems. I have described the procedure here:

This one is in Matlab!

Thank you very much. I have to study more about your posts.
