Hi @mdavids-cfs, I could be wrong on this. But, I think that UMFPack is a serial solver? If you want to use MPI (--with-parallel), we need to use a different...

Hi @mkofler96 I guess that the error indicates that you are trying to set the matrix element which is not occupied (non-zero). A sparsematrix in MFEM is a [CSR matrix](https://en.wikipedia.org/wiki/Sparse_matrix#Compressed_sparse_row_(CSR,_CRS_or_Yale_format))...

Hi @silverrose-llnl This is in fact complicated issue. HessianCoefficient is defined in mesh-optimizer.hpp The routine in mesh-optimizer.hpp is not built as a part of mfem, and they don't exit in...

Yes. But, I think the following set of lines in bilininteg.i https://github.com/mfem/PyMFEM/blob/master/mfem/_ser/bilininteg.i#L1 https://github.com/mfem/PyMFEM/blob/master/mfem/_ser/bilininteg.i#L40C1-L44C38 are a simpler demonstration showing how to turn on director class in Python wrapper.

Great idea. Running minimum set of build and example test would be very helpful to detect an issue ### building 1) python setup.py installl --mfem-branch=master 2) python setup.py install --with-parallel...

I already tried to skip it by %ignore directive in SWIG, but it does not work, probably because this line does not make sense at all for SWIG. While we...

I think I was able to fix the original issue. Then, I am facing another build issue on MacOS. The compiler is complaining the same header file. This is not...

@pazner, Thank you for prompt response. The compiler is from Apple default. (/usr/bin/c++), and --version spits out the following ``` Apple clang version 14.0.0 (clang-1400.0.29.202) Target: arm64-apple-darwin21.6.0 Thread model: posix...

@panzer, thank you for your advise. After a lot of trial and error, I found that I need to set -std=c++14, instead of c++11. Following is an example of compiler...
