Ошибки modal анализа

Всем привет! Делаю расчет осевого вентилятора, понимаю, что скорее всего мне не хватает мощности ПК, но хочу хотя бы как-нибудь сделать расчет. Modal выдает такие ошибки, что можно сделать? Они возникают только если в сборке есть болты, гайки и т.д. Если убрать все крепежные элементы расчет получается
