this is my project while running the analysis following error shows
An error occurred while projecting a field because of an empty node list. If you use a contact with an active position tolerance, please check the tolerance value and increase it if necessary to avoid an empty contact definition.
I increased the tolerance value upto 0.1m still it is showing the same error. How can I fix this??
Hi @kperiyasamy_d!
Quite sure that you need to fix your CAD here as the tolerance is higher than your distance set in the contacts settings. You have intersectioning/overlapping parts that will only cause you trouble. Fix that first and I am sure that this will make things easier for you (as well as for the solver) 
Best,
