Error #312 Negative or Large Compliance

Hi,

I've checked the forum on this issue and I see some problems are regarding BCs, material properties and connectors and I am not sure which problem I am facing.

I have attached a screenshot of the error message and attached the output and fem file.

I have tried to add more BCs in case it was under constrained but this did not solve the problem. I will not change the material properties to see if this fixes the problem.

The likely cause is that your model is under constrained. This means that your problem will have no stiffness/ infinite compliance in this direction. I would check your BCs and make sure they make sense. It could also me missing/ incorrect material properties and/ or contacts.

Hope this helps

Thank you so much. Adding more constraints fixed the problems although I didn't check how changing properties would affect the final solution.
