Some of your questions are so vague that it is hard to make any informed suggestions. How would you respond if you got a request from someone to tell them how to choose the best vehicle? (Who is going to be driving it? How many passengers do you need to carry? How much weight do you need to be able to tow? How much secured cargo space do you need? What are the weather conditions where it will be driven? What type of terrain does it need to traverse? ...)
I know very little about about ME and nothing about Ansys CFD. Are you trying to build a cluster to support hundreds of users submitting thousands of jobs? Are you trying to build a cluster than can break a single huge job into thousands of threads and run all of those threads simultaneously? Do you have any experience writing thread-safe code?
Can you use only open-source software? Of course you can! You can write all of the code you need and make it available for everyone to use as they see fit.
Does open-source software already exist for all of the code you want to run? How can we guess at that from what you've told us? We have no idea what all of the code you want to run needs to do.
If you don't know the difference between a heterogeneous cluster and a homogeneous cluster, you probably don't have the background needed to design the cluster you want. Please consider hiring an architect with experience setting up and running an HPC data center who you can sit down with and discuss budget, capabilities, computing projects to be run, users to be supported, software to be run, software to be written, etc., etc., etc. Setting up an HPC data center is a very complex, expensive undertaking.

IPCLUSTER(1) IPCLUSTER(1)
NAME
ipcluster - IPython parallel computing cluster control tool
SYNOPSIS
ipcluster {piexec,local,mpirun,pbs,ssh} [options]
DESCRIPTION
ipcluster is a control tool for IPython's parallel computing functions.
IPython cluster startup. This starts a controller and engines using various approaches. Use the IPYTHONDIR environment variable to change
your IPython directory from the default of .ipython or _ipython. The log and security subdirectories of your IPython directory will be used
by this script for log files and security files.
POSITIONAL ARGUMENTS
The first positional argument should be one of: {mpiexec, local, mpirun, pbs, ssh}, which are the available cluster types.
For detailed help on each, type "ipcluster TYPE --help". Briefly:
local run a local cluster
mpirun run a cluster using mpirun (mpiexec also works)
mpiexec run a cluster using mpiexec (mpirun also works)
pbs run a pbs cluster
ssh run a cluster using ssh, should have ssh-keys setup
OPTIONS
-h, --help
show help message and exit
EXAMPLE
ipcluster local -n 4
This command will start 4 IPython engines on the local computer.
