Hi @sshiraiwa, The problem you were running into is caused by the compiler flag: ``` -isysroot /Library/Developer/CommandLineTools/SDKs/MacOSX12.sdk ``` This is sets the "system root directory", which will cause the compiler...

There shouldn't be any issue setting -std=c++14 (or any standard newer than C++11), but just FYI that fix doesn't work for me. Are you running on an older version of...

Thanks @sshiraiwa. Closing for now. Please re-open if it continues to be an issue.

One way of doing it is to define a "coefficient" $\boldsymbol{f} = q \nabla T$, and then use `VectorDomainLFIntegrator` to compute the linear form $(\boldsymbol{f}, \boldsymbol{v})$. You can represent $q$...

Yes, this coefficient should be exact (at a given point, it should evaluate exactly the term $q \nabla T$). In order to compute the integrals in the linear form exactly,...

Merged in `next` for testing...

Thanks @dtaller. Is this ready? If so I'll start the review process.

One more consideration: if the monitor is used to indicate convergence, then the same convergence criterion can be used across different solvers. You don't need to create separate derived classes...
