cweld conversion (from elemid to partpat)
Altair EmployeeHello,
i use fe absorb to absorb nastran cweld (nastran80-88 type) then unrealize all of them.
then i change weld type from elemid to part pat and realize it.
at the end, i lose GS value of cweld elements. What could i do ? what is wrong with these method ?
thank a lot

Are you realizing with the correct config? The 'GA-GB PARTPAT' config doesn't populate the GS value. Only the 'GS PARTPAT' does. Both configs are considered part pat.

i am sure i realize with GA-GB PARTPAT and i recieve following errror. i check the manual
** USER FATAL MESSAGE 316 (IFPDRV)
ILLEGAL DATA ON BULK DATA ENTRY CWELD
CWELD 6765647 2 PARTPAT 954511 954512 +000C09
++000C095447 5447 +000C0A
format is like that
CWELD EWID PWID GS 'PARTPAT' GA GB
PIDA PIDB
XS YS ZS
also I check the card/elems in hyper. then i see GS=0
so i conclude there is missing GS value ?

For this config GS should be blank, so I don't think that is the problem. Just for clarification, are you using Radioss bulk for the solver? Looks like you were using a Nastran configuration previously.
If so, try puptting a connection location in the card and see if that works. (yours are blank, or you did not include the third line) If it does, then I will check on why those fields are not being populated.

i use nastran as a solver.
i put the G5 value manually but it gives error again.

GS=934009
so GS is not problem but what it is ?

You will have to check the NASTRAN manual for details on this error message.
I was referring to manually populating the XS, YS, and ZS fields, as it looks like they are required for the option you are trying to use. Leave GS blank.
