Hello,

Can you send us also the mesh, so that the example can be executed?

In jupyter, you can (under File/Download as menus) download the notebook as a Python script and send that script - it is easier for me to run and more light-weight.

Hello, sfepy community

I am new to this tool, and I have been exploring it for some time. I got some issues related to Nonlinear diffusion's equation problem.

As I took 100mm*100mm domain and left boundary I fixed it to 25 degree celsius(gamma1) and Right boundary(gamma2) as 500 degree celcius.

Initial condition is taken as 25 degree celcius I took a nonlinear function as 2T, I tried a lot, however the solution was reaching to infinity, I mean it was showing (sfepy: linesearch: iter 2, (nan < nan) (new ls: 1.000000e-01)).

I attached the file below For Your Reference.

Any lead or help will be highly appreciated Thank you for your help!
