# System PDEs - Comsol

#### ManuelF

Hello!
I have to solve a system of PDEs with Comsol and do not know where to start ...
This is the system:
$$&u_{,x}+v_{,y}=k y+h x\ \ \ &in\ \mathcal{A}$$
$$v_{,x}-u_{,y}=k x-h y\ \ \ &in\ \mathcal{A}$$
$$u n_x+v n_y=0\ \ \ &on\ \partial\mathcal{A}$$

$$\mathcal{A}\ in\ \mathbb{R}^2$$,$$\boldsymbol{v}=(u,v)$$, $$h,k\ \in\mathds{R}$$ and $$\boldsymbol{v}=(nx,ny)$$ is the normal vector.
Someone can help me?
Can you send me the solution made with Comsol?
Thank you all!!!
