#110: Data recovery of results at every cycle for Nastran SOL200<\/p>\n
Data recovery results at every cycle is defined by PARAM,NASPRT,1 in bulk data section.<\/p>\n
By default, SOL 200, in addition to performing an analysis and optimization, will perform full data recovery operations at the first design cycle and upon completion of the last design cycle.<\/p>\n
If NASPRT > 0, then data recovery operations are performed at the first design cycle. At every design cycle that is a multiple of NASPRT.<\/p>\n
For example, if PARAM,NASPRT,2 and the maximum number of design iterations requested is 5, then data recovery is obtained at design iterations 1, 2, 4, and 5.<\/p>\n
If NASPRT < 0, then no data recovery operations are performed.\n<\/p>\n","protected":false},"excerpt":{"rendered":"
