[Paraview] Minimal setup for coprocessing in a Fortran solver

[Renato Elias]

Hi Andy,

thanks for helping. I was doing my homework and building a very simple
Fortran90 example aside PV distribution. This example follows attached.

As you suggested, I've built this example using the ParaView source code
structure. The user just needs to uncompress the zip file in the
CoProcessing/Adaptors/FortranAdaptors folder that it'll create an
EdgeCFDAdaptor and insert an BUILD_EDGECFD_ADAPTOR entry to the CMake setup
for ParaView building. The adaptor itself compiles without any problem. I
also included a Test folder with a small Fortran program that should mimic
a transient simulation calling ParaView coprocessing. Now, I'm a little bit
held trying to understand the next steps. I've created a simple pipeline
and exported the coprocessing.py Python script to be used by the adaptor
but I'm not quite sure about how I'd make things work together. Do I need
to start ParaView first? Does the coprocessor open PV automatically?

Regards

Renato.

obs.: It should be great have more Fortran90 examples in the ParaView
distribution since there's still a bunch of scientific codes running in
Fortran.
