Ray: The tgcm15 job for Gonzalo is stopping in the usual place in settei: S10(I,1) = 1.57E-12*exp((2.4E4+0.3*(F(I,NTEK)-1500.)-1.947E-5 1 *(F(I,NTEK)-1500.)*(F(I,NTEK)-4000.))*(F(I,NTEK)-3000.)/(3000. 2 *F(I,NTEK)))*S10(I,1) I think the argument to exp() is too big. This happened even in the run with dipmin=0.1 (and other mods in modsrc.gonz), with STEP=120. It stops after about 6.5 hours (starting from /ROBLE/tgcm15r/peqsm41 at 10,0,0). --Ben
