December 15, 2020 at 1:27 pmAshish KhemkaForum ModeratornFor the SMART crack model do you have the Auto Time Stepping set to Program Controlled?nSMART crack growth will only calculate the first result in that case because the solver will default to one substep. For calculating more increments you need to specify more substeps. For instance, set Auto Time Stepping to 'Off' and then specify the number of substeps.nRegards,nAshish Khemkann
