This cluster has 64 cores. As I don&#8217;t have an ISAT table for that many cores, I need to start without the ISAT table.nFluent stops before calculating the first iteration and hands out following error message:n********** ISAT_ABORT **************n routine = isat_leaf_init                                                     n location =           1                                                       n message = svd failed, INFO=                                                  n        38                                                                     n****** END ISAT_ABORT **************n ell_radii: info, n, lwork, work(1) =          39         40      16800n  1400.00000000000    n sv = n          NaN         NaN         NaN         NaN         NaNn         NaN         NaN         NaN         NaN         NaNn         NaN         NaN         NaN         NaN         NaNn         NaN         NaN         NaN         NaN         NaNn         NaN         NaN         NaN         NaN         NaNn         NaN         NaN         NaN         NaN         NaNn         NaN         NaN         NaN         NaN         NaNn         NaN         NaN         NaN         NaN         NaNnI&#8217;ve been using another reaction mechanism and never got this error message.
