Hi everyone,

 

We are currently experemementing lattice optimization on a cubic (just a try in order to experiment more difficult pieces after). We created the model on Hypermesh, selecting lattice optimization. But , in Optistruct, when we open the ..._lattice.fem, we have the following error :

 

*** INTERNAL PROGRAMMING ERROR ***

 in file 'dsetio_inc.h', at location #132.

 

 

Please note that we already tried to open the results of the topological optimization using directly Optistruc and Hyperview from Hypermesh. We had good results regarding the modelisation we have done.

 

Thank's for your help !

    Hi @Lagolito

     

    You are trying to run _lattice.fem in OptiStruct and you get this error correct?

     

    Can you share the entire .out file, please?
