When using the Run Serial switch you will want to first go into the Algorithm Setup within the Run mesh studies menu. You will want to set the Number of threads to run (inner) to a high value similar to the number of threads your machine can run. There is also a feature that lets you limit the number of trials for finding a neighbor (as sideways edge). This should speed up cases when you have long range propagation and few good neighbors to connect towill find the requested sideways edges, but only use a limiter number of attempts to find them. Both of these settings are highlighted in this image:

The greyed out section just to the right of where you see yellow highlights, the switch the says “Limit propagation attempts”. This switch becomes active when you turn on check “Limit sideways edges in analysis”. You will want to avoid using a high number here because this will cause the topology report to run longer, 16 is a good value to start with. You will want to decrease this value if your topology reports are taking a very long time to run.
