| Oct 5, 2018 at 4:48 | comment | added | aluuzz | The problem is this integral 4 [Pi] nn NIntegrate[r^2 Exp[-First[ps[nn]][r]], {r, 0, R}] suppose to give me the number of Z that I assign it in the above of my code, but it does not. | |
| Oct 5, 2018 at 4:43 | comment | added | Alex Trounev | The question is, what do you want to fix? We do not know what problem you solve. | |
| Oct 5, 2018 at 4:36 | comment | added | aluuzz | you are right. How to fix it? | |

The code contains errors as reported by the system, for example ParametricNDSolveValue::ndsz: At r == 0.011814321203945158960724620268818668925976400238503304865530., step size is effectively zero; singularity or stiff system suspected.`

| Oct 5, 2018 at 4:25 | comment | added | aluuzz | because this 4 [Pi] nn NIntegrate[r^2 Exp[-First[ps[nn]][r]], {r, 0, R}] is Z | |

How do we know that Tot = Z? This is not visible from your code. Publish the original model so that we can determine where you are wrong.
