Hello,everyone

I have 3 questions related to calculating random fatigue life in Fe-safe 2017 .Thanks 

1) I use material steel DC01 in life calculating ,set the UTS is 270MPa ,but in the finally Fe-safe submitting check panel ,the UTS data shown 0, why 

2) During Fe-safe calculating process , there are a lot warnings shown below . Do these warnings effect the final results ?

3) In this case ,the random fatigue life of the brace shown below. According to my experience ,i think the life results is abnormal due to the life results on the fillets are also very large (shown 7) , the max. log life of the stress is 7 . I think there is a up threshold . how to increase the threshold from 7 to 10
