| Cause Category | Typical Culprits | |----------------|------------------| | | Highly distorted tetrahedra, inverted elements, or thickness changes too abrupt | | Material data | Incomplete viscosity coefficients (Cross-WLFL model) or missing transition temperature | | Process settings | Too low melt temperature, too fast injection, or unrealistic packing pressure | | Geometry | Zero-thickness regions, sharp corners with no radius, or micro-features smaller than mesh size |
Autodesk Moldflow is an industry-leading simulation software utilized for validating and optimizing plastic injection molding designs. However, users—particularly those using network licenses—may encounter a frustrating roadblock: . autodesk moldflow error 99998
Close all instances of Moldflow Synergy.
Ensure the solver points to the correct ALS service:
Use the Mesh Repair Wizard to find and fix overlaps or intersections. | Cause | Primary Solution | |---|---| |
Required license for fiber is not available..." or " Error 99998
3D meshes with millions of elements demand massive computational memory. If Moldflow hits your hardware ceiling, the solver crashes instantly with Error 99998.
Sometimes, graphics drivers or display settings can cause issues: Close all instances of Moldflow Synergy
Avoid uniform global mesh refinement on complex parts. Use local mesh density controls on sharp radii, gates, and thin-walled rib sections to keep the total element count manageable.
Firewalls are blocking communication, or the network timeout is reached before a license is granted. Top Troubleshooting Solutions
If using a 3D mesh, check for tetras with extreme internal angles or zero volume. 3. Optimize Windows Virtual Memory (Paging File)
Go to the tab and click Change under Virtual Memory.
