Solver fails to solve the following nonlinear system of equations (4th order terms)
```
th = 2400
tk = 320
Solve({th^4 - tw^4 -1.77E-6*qw == 0,
tw^2 - t1^2 +2454*(tw - t1) - 0.2319 *qw ==0,

### Current implementation
Broadly speaking, the [MnaSolver](https://github.com/sogno-platform/dpsim/blob/master/dpsim/include/dpsim/MNASolver.h) class sets up system related objects (MNA-components,…

By using a nonlinear equation/complementarity problem solver or a polynomial equation solver (if any).
What packages are available in Julia (and in Python)?

As I understood, nonlinear motion constraints are not supported by sympy.physics.mechanics.
They are dealt with in detail in the book _Dynamics, Theory and Application of Kane's Method by Carlos Roith…

Does PHCpy support solving systems of nonlinear equations with complex variables, or do I have to split them into real and imaginary parts before feeding them to the solver?
