Modelling problems leading to large file sizes

There may be a problem in your model which causes numerical problems resulting in excessive file sizes during solution.

We would recommend that you search your LUSAS Solver text output file (*.OUT) for the word "WARNING" and then the word "ERROR".  In general, the first warning or error in the *.OUT file is the most important, excluding  

 ***WARNING***  LARGEST NODE NUMBER IN NODE COORDINATES EXCEEDS LARGEST IN ELEMENT NODES  

The user area includes a list of common warning messages with links to solutions and theory pages.
