Отслоение в композите

[Aldar 4]

Здравствуйте уважаемые.

Рассматривается задача отслоения. По идее, в середине должно произойти отслоение. Свойства материалов слоев взяты из библиотеки ansys. 

В принципе все сделал, но расчет не проходит. Не могу найти ошибку.

Выходит: 

Warning: "Not all Named Selections were successfully written because one or more names are not valid for the solver"

Error: "An unknown error occurred during solution.  Check the Solver Output on the Solution Information object for possible causes."

Думал настройках solve proccesing settings, но вроде все нормально.
