When I run a calculation I got a warning of instability in for example node 50. If I stabilize that node and run the calculation once again I got a new warning of instability in a totally different node in the model, if I stabilize that node I got a new warning in another node and so on… Why is it like this and is it possible to get all warnings in the first calculation?

Please check the already existing topic of this forum:
In general the instabilities of types 1 and 2 cannot be ignored. The type 3 in some cases may be ignored but in all cases you should determine the cause of this instability first as well as examine the results (especially displacements and rotations of nodes as well as reactions vs. applied load) very carefully.
