Modeling reinforced concrete in ADINA, is ok. But I can not get the cracks displayed in a vector plot. Not crack_flag, neither crack number in band plot, that is ok.
a first check is that you save the crack information to the porthole file. This is no longer default. In the AUI you use Control/Porthole/Volume and switch off Save Only Selected ... to get the old default, to save all results. OR, you use Control/Porthole/Select Element Results and Add the results you want.
If this doesn't solve your problem, please come back.
