| Nov 26, 2021 at 11:18 | comment | added | Jose Enrique Aroca | Hi, 𝜆 is just a positive constant with any arbitrary value. I have added this to the code and my attempt to include this factor. The problem is that with my first-order method, the results are not accurate enough. | |
| Nov 26, 2021 at 6:26 | comment | added | Alex Trounev | What is $\lambda$ in your model? | |
| Nov 25, 2021 at 14:59 | comment | added | Jose Enrique Aroca | If it helps, I am trying to implement your iterative method for this new form of the equations (as it was more precise) but for some reason, it's giving me inaccurate results beyond t=1 | |
| Nov 24, 2021 at 18:34 | comment | added | Jose Enrique Aroca | I really don't understand your question. I managed to fix my code and I took your advice on how to plot things for different values using Module. My problem here is that when I add the last factor the finite difference algorithm is not accurate enough and this leads to inaccurate results. | |
| Nov 23, 2021 at 3:36 | comment | added | Alex Trounev | Did you test your code or you use it as it is? In my answer there are 3 methods are compared to test your code. | |
| Nov 22, 2021 at 16:20 | comment | added | Jose Enrique Aroca | This code is similar to what I posted previously. I finally didn't use the iterative solution you proposed. I managed to make a small adjustment to what I posted to make this working and now I have to include an extra factor, but as this is outside the integral, I am not sure how to. | |
| Nov 22, 2021 at 16:13 | comment | added | Alex Trounev | Did you use code from my answer or this is a new code? | |
| Nov 22, 2021 at 8:59 | comment | added | Jose Enrique Aroca | Hi, thank you very much for your comment! Indeed, we discussed a similar problem, but the introduction of a new function which is only dependent on t makes things more complicated. I thought that creating a new question would be more useful for new people to see it and add there ideas on how to solve it! | |
