Hi,<\/p>\n
I’m trying to run a modal analysis with pre-stress.<\/p>\n
I wrote this under:<\/p>\n
<\/p>\n
\n
\/SOL<\/div>\n
!PreStress<\/div>\n
ANTYPE,0<\/div>\n
PSTRES, ON<\/div>\n
SOLVE<\/div>\n
FINISH<\/div>\n
<\/p>\n
\/SOL<\/div>\n
!Modal Analysis<\/div>\n
ANTYPE,2<\/div>\n
MODOPT,LANB,5,0,0, ,OFF<\/div>\n
EQSLV,SPAR <\/div>\n
MXPAND,ALL, , ,YES <\/div>\n
LUMPM,0<\/div>\n
PSTRES,ON<\/div>\n
SOLVE<\/div>\n
save,analyse_modale,db,,all<\/div>\n
<\/div>\n
<\/div>\n
When ran separatly, both step works fine: the static step is correctly computed, and the result match with analytical solution.<\/div>\n
<\/div>\n
However when ran before the modal analysis the db doesn’t store the static solution. I’ve tried to multiply “save” command, but it didn’t work.<\/div>\n
<\/div>\n
Idealy I would like a single .db with the first static step and the second modal step.<\/div>\n
<\/div>\n
Do you have any idea as to why it doesn’t work ?<\/div>\n
