Ansys General Error New!

Prevention is better than debugging a 36-hour simulation that failed at 99%.

More often than not, a General Error is not a physics problem but a hardware or resource limitation. ansys general error

At its core, the General Error is rarely a problem with ANSYS itself, but rather a symptom of a mismatch between the user’s model and the laws of physics. The most common cause is corrupted or poor-quality mesh. Finite element analysis relies on mathematically perfect elements; a single highly skewed or degenerate element can produce infinite stiffness values, causing the matrix solver to crash. Similarly, contact definitions that create abrupt changes in stiffness or boundary conditions that over-constrain a model can lead to numerical instability, manifesting as a "General Error" halfway through a simulation.
