My appologies, I was making a mistake, or at least I was not using exactly the same parameters with the two datasets. With the dataset that failed I mistakenly had a much higher value for “Base num. tetra cells” in the Mesh Prep Job. When I use an identical value it seems to run fine (i.e., currently it has completed 200 iterations where as previosly it failed before starting any). So the “Base num. tetra cells” in the prior Mesh Prep Job was the key parameter to change.
