Dear all,
I'm trying to solve a PDE that consists of erfc(x) and exp(x^2) like the file attached below, which is simply a poisson's equation.
Since it has an unknown boundary condition, F electric field at position x=0, I tried 'minerr(F)' type resolution with F declared beforehand by initial guess.
Unfortunatlely, it keeps saying that F in the 'miners' syntax has not been defined.
Could anyone can help me?
Thank you in advance for your help.
