A guide to troubleshooting your structural model if it is not solving
There are a wide range of reasons why your structural analysis model will fail to load. There are a number of basic liste des erreurs tel que Add a Support, Add Loads and Add a member. But what happens if you have your model built but but it is still not solving? SkyCiv has put together a guide of how to troubleshoot your model.
Does your model have cables?
Cables use non-linear analysis that require convergence to solve successfully. Cette convergence peut entraîner des problèmes et empêcher le solveur de terminer.
Quoi essayer: Voici un guide sur les éléments à vérifier si votre cable analysis is failing to solve.
Avez-vous modifié vos fixités de fin de membre?
Il est important de savoir que changer les fixités d'extrémité des membres de quelque chose de différent à FFFFFF (to model things like pinned connections, roller connections, truss members etc..) can affect the stability of the structure. If a structure is inadequately connected, it will be unstable and the solve will fail.
Quoi essayer: change all your members to fully fixed FFFFFF (you can do this quickly by using CTRL + A (select all) then multi-edit the members by clicking Membrures on the left input).

Are your supports fully fixed?
Very similar to the above point on member end fixities. If you have changed any of your support fixities to anything different to your typical fixities (FFFFFF, FFFFFR, FRFFFR), it may cause issues in the model. Examples include, FRFRRR
Quoi essayer: change all your supports to fully fixed FFFFFF (you can do this quickly by using CTRL + A (select all) then multi-edit the supports by clicking appuis illimités on the left input).
Are you using Member offsets?
Member offsets create small rigid members between the node and the end of member. These can conflict with member end fixities and support fixities, so it’s a good idea to check if this is causing the issue.
Quoi essayer: remove all offsets in members and try to solve (use the datasheet or multi-edit to do this quickly and easily)
