The Thread[Rule[{a, b, c, e, e2, l, b2, dd, L, pt0, pr0, v0, y0}, ConstantArray[1, 13]] sets all of the parameters to 1, i.e., assigns "numeric values for all parameters". Even with these assignments, DSolve cannot solve the simplified system. Complicating the problem by leaving any of the parameters as symbolic is not going to help DSolve.

| Jan 17, 2018 at 6:25 | comment | added | Wat Watson | What do you mean by "numeric values for all parameters"? Can DSolve find the functionality if I determine some parameters and not all of them? | |

Since DSolve cannot solve the system with numeric values for all parameters, it is extremely unlikely that a solution can be found for symbolic parameters.

| Jan 17, 2018 at 6:13 | comment | added | Wat Watson | Actually, I need to find a functionality for the solutions. | |
| Jan 17, 2018 at 6:11 | comment | added | Wat Watson | Thank you for your answer. But I prefer to solve them without ndsolve to understand the effect of each parameter. Do you think it could be possible to do that or not? | |
