@user55777 Explain what this model describes. Then I will explain to you why there should be Log[Abs[(1 - v0)/(1 - v[x, t])]]

@user55777 From a physical point of view you should use Log[Abs[(1 - v0)/(1 - v[x, t])]]

Physically, how close to 1 can v become?

| Sep 10, 2019 at 3:01 | comment | added | user55777 | @bbgodfrey yes, both solutions u and v should be real because they are for real physical quantities. The problem is how to add the constraint in my first question. Thank you. | |

| Sep 10, 2019 at 2:58 | comment | added | bbgodfrey | Is there reason to believe that the exact solution actually is real over the entire domain? | |

For the second problem use funcSol[x_?NumericQ, t_?NumericQ]:= ... so that NIntegrate will get numerical input as it expects.
