Getting Nastran results from pch file

Is there any way to load Nastran results (structural/thermal) from pch files in NX instead of op2?

 

op2 takes a lot of space so I would rather keep the pch files. 

 

Other suggestions are also welcomed! (e.g. exporting to some other format or so)

 

On the other hand, if there is no work around and I must use op2 to view the Nastran results, how can I avoid pch files being written in order to save space?

 

Thank you!

Re: Getting Nastran results from pch file

pch would arguably be worse as it is ASCII instead of binary...  But they will compress nicely (probably close to an op2 size). pch will be written only if you have some output directed at the punch file (as in FORCE(PUNCH)=ALL)
