the variables below 8m/s arenot okay, but the variables more than 9m/s are okay.

After integration, I got error continually. Before integration, I got result's values.

please help me. I thoght to solve my problem for many hour, but I couldn't handle it

In cases like that you have to follow your calculations until you end up at the one that really throws the error. Thats quite "fun" in your sheet as your functions are hopelessly nested. CT0 call T, T calls t, t calls ..... etc.

In your specific case its the solve block for ar and a'r which throws the error when fed with the values you provide and when used with r[15 (it quite possible tha other elements of r throw an error, too; I haven't tried). If you think that you should get a solution with those values, too, you will have to recheck the equations and all functions related to that solve block.

I rechecked all functions related to "solve block"

But they are no problem..

And I changed CTOL 10^-2 and then I can get ar' value.

But I now can't get my CT value and I can't trust 10^-2 because 10^-3 is common.

so I need to get result's value in case of 10^-3.

Have you good idea to solve my problem?

But is this solution valid? Is it reliable? I meant that you will have to check the meaning of the equations in your solve block and try to get a solution for those values manually by some means so you can check the validity.

But I now can't get my CT value

So possibly even other combinations of values in the calculation of CT throw an error, too. You have to chekc all of them, I just picked the first one I came across.

so I need to get result's value in case of 10^-3.

What makes you so sure that there really exists a solution? Find it manually yourself by some means, then you can blame Prime for not doing so.
