We have an exciting announcement about badges coming in May 2025. Until then, we will temporarily stop issuing new badges for course completions and certifications. However, all completions will be recorded and fulfilled after May 2025.

Does this error occur during the bolt pretension step?
Is Plasticity defined for the bolt material with a zero Tangent Modulus?
If so, use the bolt diameter to calculate the bolt area A in square mm.
Calculate the stress in MPa using F/A where F = 20106 N
Compare that stress with the Yield Strength of the bolt material in MPa.
If the stress is larger than the Yield Strength, that is the cause of this error.
