Hello everybody,
I have a numerical model for a thermal spray process which is described by a relationship of the type:
![](https://www.mathworks.com/matlabcentral/answers/uploaded_files/292489/image.png)
where x,y and z are the three space dimensions and t is the time. The phenomenon is described by the following type of First Order 2D PDE:

I can obtain both Initial Conditions and Boundary Conditions but they will be different each time I apply the model.
I tried to understand if pdepe was feasible but I have too many variables for it. I also tried with Partial Differential Equation Toolbox but my equation does not match the Divergence Form. I think this problem could be solved with the characteristics method but changing IC and BC makes it unfeasible. Is there any Matlab function or numerical method to solve this equation numerically?

It's too complicated, don't know how to solve. I thought FDM method can be applied, but it's not
