Troubleshooting

Problem Situations

A Load Transfer Error Has Occurred.
Although the Solution Failed to Solve Completely at all Time Points.
An Error Occurred Inside the SOLVER Module: Invalid Material Properties
An Error Occurred While Solving Due To Insufficient Disk Space
An Error Occurred While Starting the ANSYS Solver Module
An Internal Solution Magnitude Limit Was Exceeded.
An Iterative Solver Was Used for this Analysis
Animation Does not Export Correctly
Assemblies Missing Parts
CATIA V5 and IGES Surface Bodies
Illogical Reaction Results
Large Deformation Effects are Active
One or More Contact Regions May Not Be In Initial Contact
One or more MPC contact regions or remote boundary conditions may have conflicts
One or More Parts May Be Underconstrained
Problems Unique to Background (Asynchronous) Solutions
Problems Using Solution
Running Norton AntiVirusTM Causes Simulation to Crash
The Correctly Licensed Product Will Not Run
The Deformation is Large Compared to the Model Bounding Box
The Initial Time Increment May Be Too Large for This Problem
The Joint Probe cannot Evaluate Results
The License Manager Server Is Down
The Solution Combination Folder
The Solver Engine was Unable to Converge
The Solver Has Found Conflicting DOF Constraints
Unable to Find Requested Modes
You Must Specify Joint Conditions to all Three Rotational DOFs
