Hello everybody ! I made a case of a plunging airfoil. I get a different error message for different choice of the number of cores in decomposePar. You can notice that the simulation ran longer before crashing on a single core. Any suggestions? Here is the link to the github repository if anyone wants to take a closer look at the case file. https://github.com/pruthvi1991/pimpl.../onemeterplate
To run the case execute ./runAmbient
