Warning

Cause and Solution

W697

W539

W697 - Iteration convergence failed (R>0)

W539 - Iteration convergence failed (D>0 and R<0)

Simultaneous friction and single-directional restraint iterations did not converge. Follow E828 error recommendations

W697 - Reaction in restricted direction (R>0). Example: upward reaction at resting support

W539 - Displacement in allowed direction with reaction in same direction (D>0 and R<0)

D = displacement in allowed direction, R = reaction in allowed direction

W541

W693

W694

W696

W542

W541 - Solution integrity check failed (D<0)

W104 - Solution integrity check failed (D!=0)

W693 - Solution integrity check failed (|D/k-Z-R| < 0)

W694 - Solution integrity check failed (D>DD)

W696 - Displacement and friction force vectors not parallel

W542 - Solution not obtained (problem x)

Deformation check failed. Solution accuracy lost. Add more markers or adjust marker spacing. Follow E828 error recommendations

W541 - Displacement in restricted direction of single-directional restraint (D<0)

W104 - Non-zero displacement in double-acting restraint (D!=0)

W693 - Spring deformation check failed (|D/k-Z-R| < 0)

W694 - Displacement exceeds gap value (D>DD)

W696 - Displacement and friction force vectors not parallel

W542 - Send project file to technical support

D = displacement, R = reaction, k = flexibility, Z = precompression, DD = gap

W815

Solution integrity check failed (Fric!=Kfric*R)

Friction force does not equal friction coefficient times reaction force. Send model file to developers

W416

Insert reducer at diameter change node

Add reducer element between pipes with different diameters

W582

W583

Force/moment limit exceeded

Support load exceeds maximum value defined in support properties

W632

Allowable restraint subsidence applied

Small support subsidence applied to improve single-directional restraint convergence. Informational message - no action required

W305

Pipe lifted off support

Single-directional restraint disabled - not carrying load.

Warning only - no code violation. Pipe moves upward off support. Remove support if lifting occurs in all operating modes. If lifting occurs only in hot state, pipe returns to support when cold. Consider potential vibration and displacement issues. Engineer discretion required based on experience or company standards.

W670

Hanger rod rotation exceeds limit

Limit defined in Project Settings. Default: 5° (Russian codes), 3° rigid/4° spring (Chinese D-ZD2010). Increase rod length to resolve
