Clustered network. How to resolve?

[lucianoguedes8]

Greetings.

I set my code to run StokesFlow algorithm and occuried an error that says my network is clustered. With IA help, I understood that my network is with disconnected pores.

100 # Rodar o algoritmo para resolver o balanço de massa em cada poro e computar a pressão

250 msg = ("Your network is clustered, making Ax = b ill-conditioned")
--> 251 raise Exception(msg)

Exception: Your network is clustered, making Ax = b ill-conditioned**

So, the IA recommended a code to remove these disconnected pores (disconnected clusters), pointing an need to run the algorithm with only the main cluster.

How can I do this?

Have you tried the advice in this example yet?

Oh, I didn't found this. I will try this example now.

Thank you, professor.
