If you'd like to troubleshoot a specific software, let me know: Which are you using? (ANSYS, MATLAB, etc.) Are you on a student or professional license?
Vendors offer "Student" or "Lite" versions for free or at a low cost. To prevent these versions from being used for high-end industrial design, they cap the problem size. This forces professional entities to upgrade to "Research" or "Enterprise" tiers.
Please reduce the problem size or contact sales to upgrade your license. your product license has numerical problem size limits
Problem Size Too Large Body: Your current license tier does not support the numerical size of the problem you are attempting to solve.
| Metric | Description | Example Limit | |--------|-------------|----------------| | Variables | Decision variables in your model | 500 | | Constraints | Linear/nonlinear constraints | 500 | | Nonzero coefficients | Nonzero entries in constraint matrix | 5,000 | | Integer variables | Variables restricted to integer values | 200 | | Elements (FEA/CFD) | Mesh or grid elements | 50,000 | If you'd like to troubleshoot a specific software,
What is the (nodes/variables) of the model you’re trying to run?
Some licenses are tuned to the hardware they sit on. A license might limit the problem size because the current hardware configuration cannot solve larger matrices within a reasonable timeframe, protecting the user experience. Immediate Steps to Resolve the Error To prevent these versions from being used for
While numerical problem size limits can be restrictive, there are some potential workarounds and solutions:
Most technical software packages—particularly those used for Finite Element Analysis (FEA), Computational Fluid Dynamics (CFD), and complex mathematical optimization—quantify the "size" of a problem based on its complexity. The limit usually refers to one of the following metrics:
For [Product Name], problem size refers to one or more of the following numerical metrics, depending on your license tier (e.g., Community, Professional, Enterprise):
When implementing this, it is helpful to dynamically insert the specific numbers.
