LUSAS Solver memory allocation

For V15.0 onwards the memory allocation settings for Solver are much more automated and it is generally recommended that the following settings are not changed from their installation default settings:

  • Memory allocated to Solver array (NLPZ)  
  • Memory allocated to Solver cache (NPGS)  
  • Elements in group (MXELGP) 

If you encounter any memory related problems, or if you are using V14.7 or an earlier version of LUSAS, please email your model file ".mdl" and LUSAS Solver Output file ".out" to Support@lusas.com for advice.
