Basic checks for your model

The following "Basic checks for your model" list is useful for identifying gross errors in a linear static analyses:

1. Check the reactions you get. Use a loadcase you can calculate by hand and compare using

Utilities > Print results wizard > Entity=Reaction, Type=Summary

It is worthwhile checking all your loadcases in this manner since the total load may usually be readily calculated and gross errors can be identified in this way.

2. Check the deformed shape that you get. How does this compare to your expectations for the behaviour of the model? On reflection is it the model or the expectations that require further scrutiny?

3. Check the value of the deformations.

View > Insert layer > (check) Deformed mesh  > (check) Window Summary 

This is particularly useful in identifying problems concerning consistent units and material/ geometric properties or missing supports.

4, Check your LUSAS Solver text output file (*.OUT) for any warning messages. This may identify areas in the model which could be improved.

5. Check on mesh refinement is necessary for all FE analyses.  A coarse mesh may produce results which are unconservative for design purposes.
