If you are not sure where to begin, here are a few practical checks that often help you identify the how to resolve an issue quickly in FEM-Design. Even small observations can make model behaviour easier to understand and sometimes resolve the issue right away.
1. Start simple
Run a simpler analysis first
If possible, verify that the model works in a basic linear setup before moving to advanced settings.
2. Check support conditions and stability
Check supports and stability
Most serious calculation errors begin with missing restraint or incorrect connectivity.
3. Review geometry and mesh
Check geometry and mesh
Bad geometry often creates secondary errors that look like solver problems.
4. Double-check loads and connections
Check loads and connections
Unexpected load placement or weak/incorrect connections often explain strange behavior.
5. Isolate the problem area
Simplify the model
If a full model is too difficult to debug, isolate the problem area and test it separately.
These checks reflect the most common causes of FEM-Design calculation issues, including support conditions, geometry or mesh problems, connection behaviour, load setup, and result interpretation.
If you would like us to take a closer look, you are always welcome to contact support. If you have any of the details below, they can be useful, but there is no need to have everything ready before reaching out:
- your FEM-Design file
- a screenshot of the error message
- a short note about what changed before the issue appeared
- which load case, combination, or analysis type fails
- whether the issue is new or has been there since the model was created
A few details like these often make it easier for us to understand what is happening and help you more quickly. But if you are not sure what to send, that is fine too - just contact us and we will guide you from there.
