This Message Shows after I run a solver :
A solver pivot warning or error has been detected in the UY degree of freedom of node 111607 located in Surface Body. This is usually a result of an ill conditioned matrix possibly due to unreasonable material properties, an under constrained model, or contact related issues. Check results carefully. You may select the offending object and/or geometry via RMB on this warning in the Messages window..
Your help will be much appreciated
