AI Thread Summary
To solve the transport PDE u_t + x(1-x)u_x = 0 with initial and boundary conditions defined on [0,1], the method of characteristics is recommended. This approach allows for the transformation of the PDE into a set of ordinary differential equations. The expected numerical errors may arise from discretization and approximation methods used in the numerical solution. Initial conditions should be specified clearly, while boundary conditions can be set based on the physical context of the problem. A detailed understanding of these methods will enhance the accuracy of the solution.

Here's my question, friends

I have to define initial and boundary condition for a transport PDE: u_t+x(1-x)u_x=0
with x and t is between [0,1], to solve this equation, what kind of numerical method
and boundary condition do you recommend and why?

What kind of numerical error do you expect?

Detailed explanation will be appreciated in advance.

Hi , How do you do ?

you can try this answer.

u=f(lnx -ln(1-x)-t) ln() for natural log.

The method is here
