Troubleshooting

Message or symptomCause and fix
"The model has N errors; fix them to run"The model check found unsupported or floating nodes, a mechanism or members without stiffness. Click a problem to select the item; add supports or releases accordingly.
Unstable / unconverged solve in the reportThe structure is a mechanism or nearly so (residual too large). Check supports, end releases (a member released at both ends in rotation and torsion is a mechanism) and plate connectivity.
Results marked "(stale)"The model changed after the run. Press F5 (and run the design again).
A member is "Not certified"A capacity cannot be computed conservatively for that section (missing element dimensions, slender element, Pr ≥ Pe1). Check it by hand, change the section, or use a second-order method.
"No LRFD combination is selected for design"Design ▸ Setup ▸ Combinations: tick the combinations, or generate ASCE 7-22 LRFD combinations in Loads.
ASD steel designThe steel checks are LRFD only for now; use LRFD combinations. Wood and masonry checks take ASD-level demands.
Drift check shows zerosChoose a result with lateral loads (the seismic case or combination) and the right direction, then Fill from the analysis. Define story levels in Model ▸ Grid lines & stories.
Hand-off: "model could not be saved"The hand-off reads the saved model. Resolve the save problem (conflict banner or connection) and try again.
"Another job is running"Each person runs up to two jobs at a time; wait for it or cancel it in the status bar.
Read-only bannerYour licence has ended or the licensing service is unreachable. Projects stay viewable; Subscribe or Check again.
"This model changed somewhere else"It was saved from another tab or device. Load the saved version or keep yours (overwrite).
