stress bar and displacement values

[bhava9]

Thanks every one for the reply
The error was max thick/min radius some times and also length /width sometimes.i was trying to run the model even if it is giving the error but after the solution is done when i was trying to see the stress in it it is not showing any thing except the entire model in red color and it not even giving the max,min stress,displacement any thing.I tried changing the load conditions and if i do it it is giving the error the value at node has excedded the current max value of 100000 this is because of an improper constrained model.
