The Pcg Solver Has Automatically Set The Level Of Difficulty For This Model To 2 Jun 2026

If the system determines the model’s complexity exceeds baseline assumptions, the user will see the message:

When you build a finite element model (FEM) or a finite volume model, you are essentially creating a massive system of linear algebraic equations—often represented as a matrix equation, $Ax = b$. For small models, you can solve this directly. But for models with millions of degrees of freedom (DOFs), direct solvers become too memory-intensive and slow. If the system determines the model’s complexity exceeds

When you see the software has performed an automated analysis of your mesh and material properties. It detected characteristics that place your model in the "moderate difficulty" category. Common causes include: When you see the software has performed an

If possible, work in consistent units (e.g., all stiffnesses within 6 orders of magnitude). For extreme bi-material problems, consider sub-structuring or super-elements. For extreme bi-material problems
