Certain advanced settings can crash the solver reliably. For example, enabling “Large Deflection” on a model with poorly constrained degrees of freedom may cause the solver to iterate to infinity. Using a direct solver (e.g., Sparse) on a model with billions of degrees of freedom will exhaust memory faster than an iterative solver. Requesting unrealistic time steps in a transient analysis can also lead to numerical overflow. Solution: Simplify the analysis first. Start with linear, static, small-deflection assumptions. Gradually add complexity while saving intermediate results.
