Hi all,
I have a model with multiple contacts and have been using N2S contacts. I've found that in some of my loadcases, these contacts produce excessively and unrealistically high loads.
I've checked to assure there is a sufficient gap between master and slave components and have even tried changing to S2S, PARAM EXPERTNL CNTSTB... in every case the the contact in question remains an unrealistically high stress or another contact which was previously low force suddenly becomes massive.
The way I set the models up is to select contact surfaces for both slave and master and select slide option, I don't apply any clearance or srchdis values.
Anyone any suggestions? Alas I cannot share the model.
