I am getting the following error while running the MPI version of the model (hycm_std).
"puff dispersion (initd=1,2) not optimized for MPI".

Kindly advice on how to resolve this .

Thanks in advance.

You are getting that message, which also says "Simulation will continue on one processor!"
because you are running with puffs (initd=2,3 or 4). If you can change to the particle mode initd=0 for 3-d particle, or initd=1 (Gaussian-horizontal vertical puff), then it will run as multi-processor. The initd=0 is the default. Please try that.
