[FLASH-USERS] Missing Makefile in FLASH 4.8 Build for AlfvenAntenna

[ERNESTO ZURBRIGGEN]

Hi Subhasish!
I noticed two funny things in your post.
Firstly, AlfvenAntenna is not among my test problems, either in
SimulationMain or in SimulationMain/magnetoHD.

Secondly, I guess the AlfvenAntenna project should be in
SimulationMain/magnetoHD, as the MHD unit is required.
In that case, your setup should be as follows:
python3.10 bin/setup.py magnetoHD/AlfvenAntenna -auto +ug +hdf5 -objdir=object
-site=MyLinux -verbose=DEBUG

Best,
Ernesto
