ANSYS WB

ANSYS WB

ANSYS WB

(OP)
I have modeled my experimental bridge using beam and shell elements.
But when I run it in mechanical, have experienced an error as follows;
"An unexpected error ( SIG$SEGV ) has occurred"
What is the reason for that?

Also experienced with following warnings;
*** WARNING *** CP = 4.945 TIME= 17:40:43
Element shape checking is currently inactive. Issue SHPP,ON or
SHPP,WARN to reactivate, if desired.
*** WARNING *** CP = 5.164 TIME= 17:40:43
Material number 497 (used by element 13060 ) should normally have at
least one MP or one TB type command associated with it. Output of
energy by material may not be available.

In my model I have connect two line bodies by joints connections. I do not have any idea of the errors and warnings.
Can you please someone help me to solve this?
Thank you

RE: ANSYS WB

Regarding the sig#segv error, see my response to skylineblue on June 19.

Ignore the warning about shape checking. Shape checking is handled differently in WB and Mechanical APDL. IN MAPDL, shape checking is done at solution, and in WB, it is handled during meshing. WB is simply an alternate prep and post and uses the MAPDL solver. WB writes an input script which it submits to the solver, and in that script is the following:

! Turn off shape checking because checks already performed inside WB mesher.
! See help system for more information.
SHPP,OFF,,NOWARN

When the solver sees this, it issues the warning.

Also ignore the material number warning. This usually happens with elements that do not require material properties. I think the solver does a check on every material and checks for mechanical properties, and isn't smart enough to detect elements that don't actually need them. It happens with contact elements a lot, which may need material properties if certain options are used. IF a material property is needed and not provided, the solver will crash with a specific error message.
