After defining an unused SHELL131 element type, all of my previously
defined nodal displacements and forces are wiped out. Why?
|
Defect 22577 was filed and resolved in ANSYS 9.0 by including a warning message that states all element type definitions and keyopt settings should be made BEFORE nodal displacements and forces are applied (see example below). = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = nflag=0 ! nflag = 0 = define UNUSED SHELL131 element type ... /title, qt-22577 Including UNUSED Element Type SHELL131 Produces Warning /prep7 et,1,70 mp,kxx,1,100 block,,1,,1,,1 esize,,1 mshkey,1 vmesh,all nsel,s,loc,y,0 d,all,temp,100 nsel,s,loc,y,1 !d,all,temp,0 f,all,heat,77 nsel,all dlist,all ! list temperatures flist,all *if,nflag,eq,0.0,then et,4,131 ! just define element type ... dlist,all ! temperatures for nflag = 0 are gone ... *endif dlist,all flist,all finish /eof ANSYS 9.0 Warning Messages: =========================== *** WARNING *** CP= 0.000TIME= 00:00:00 When using element type 131, the program automatically issues a DDELE,all,all command when the ET or KEYOPT command is issued to change the degrees of freedom.
