I found a previous discussion on this forum that suggested that I am required to have multiple licenses to run Flow Simulation solver on multiple computers (for one problem). However, when I looked up adding computers under batch processing in SW Simulation 2010, this is what I saw:
"Specifying Computers for Network Solving Specifies a list of computers from the network on which you can run the calculation.
NOTE: The remote solver does not require to be authorized on the remote computer.
This note seems to suggest that the solver just needs to be installed on the remote computer, but not "authorized", whatever that means. But the grammar doesn't make it that clear.
