Since VH-1 does the setup of the problem in the main code, I wanted to have a way to have several different problems set up at the same time inside one source folder. My solution is as follows, let me know if you have a better way to do this. — Alex B.
make linkto create a symlink of this file to vhone.f90 before compiling.
make. This will create the file vh1-starter-<problemname> in the main directory.
make runto let it cd into the appropriate directory and run the newly compiled file, thus eliminating the need to cd between the two directories all the time.
Here is the modified makefile I use for the starter version, it can easily be adapted to the serial version, although one might find that files other than vhone.f90 differ from problem to problem:
