Ansys Your Product License Has Numerical Problem Size Limits Verified =link= -

When applying hydrostatic pressure, additional SURF154 elements can push the total over the limit even with mesh count under 64K. The solution is to make the mesh even coarser to accommodate these hidden elements.

You are attempting to run a simulation (likely a "pre-post" or "solver" task) that exceeds the size limit of your current license tier. Common Cause: Using a "Pre-Post" license to solve a large model, or having an older license file that doesn't recognize your current Ansys version limits. Immediate Fix: Check if you are using the correct license module (e.g., switching from "Pre-Post" to a full "Solver" license) or update your license file.

Do not model a symmetrical object in its entirety. If your part and loading conditions are symmetrical, cut the model in half or quarters. Use in Ansys Mechanical. Apply symmetric boundary conditions at the cut faces. Common Cause: Using a "Pre-Post" license to solve

“Maximum problem size for this license is 512000 nodes.”

Split the geometry in or Discovery (e.g., into a half or quarter model). If your part and loading conditions are symmetrical,

If you have updated your license, clear the Shared Web Licensing Credential Cache to prevent old constraints from being enforced: Close all Ansys applications. Navigate to %userprofile%/.ansys/ansysid in File Explorer. Delete cache.json and token.json . Restart Ansys.

While these licensing options provide flexibility, they also come with numerical problem size limits. These limits are designed to prevent excessive usage and ensure fair access to the software. The limits are typically defined by the number of: you may encounter:

License limits vary significantly depending on the solver and product version you are using. Your product license has numerical problem size limits…..

To effectively manage numerical problem size limits in ANSYS:

When Ansys says your license has a “verified limit,” it means your current license token only permits simulations up to a certain DOF count.

If you exceed the numerical problem size limits associated with your ANSYS license, you may encounter:
