Schwarz algorithm in Parallel

General Discussion
1

Hello,
I’m trying to solve a problem using a non-overlapping domain decomposition, I have successfully coded it in parallel using two cores manually (I have two subdomains), is there any example to use built in tools in FreeFem to solve this problem with more cores?
Thanks,
Benfanich

Either PETSc, ffddm or HPDDM. There is no reason for you to implement this by hand.

Thank you for your help.

Sorry if this a stupid question.

Is there an example on how to decompose the two subdomains and get a matching mesh using these tools ?

Because what I tried to do is decompose each one of them separately.

There are examples here FreeFem-sources/examples/hpddm at master · FreeFem/FreeFem-sources · GitHub or there FreeFem-sources/examples/ffddm at master · FreeFem/FreeFem-sources · GitHub.
