Remember: simulation is about answering an engineering question, not achieving the highest mesh count possible. Often, a 100,000-node model with proper boundary conditions yields the same insights as a 2-million-node model.
A: You can overcome numerical problem size limits by upgrading your license, optimizing your model, using parallel processing, submodeling, or using alternative software. Ansys Your Product License Has Numerical Problem Size Limits
