I am doing research on laser cutting. I am trying to remove/ deactivate the element after exceeding the melting temperature.
I tried by using following code.
/SOLU ! Enter SOLUTION
... ! Typical solution procedure
SOLVE
FINISH
!
/POST1 ! Enter POST1
SET,...
ETABLE,STRAIN,EPTO,EQV ! Store total equivalent strain in ETABLE
ESEL,S,ETAB,STRAIN,0.20 ! Select all elements with total equivalent strain
! greater than or equal to 0.20
FINISH
!
/SOLU ! Re-enter SOLUTION
ANTYPE,,REST
EKILL,ALL ! Deactivate selected (overstrained) elements
ESEL,ALL ! Restore full element set
... ! Continue with solution
But at ANTYPE,,REST it is not working.
Can anybody help me?
Hi
I do not know if this trick works in Ansys but it is commonly applied in Nastran - to turn off an element, have a duplicate element in there with a small and insignificant Young's modulus and simply give it a negative Young's modulus.value that matches the Young's modulus of the one you wish to turn off.
Hope this helps

To deactivate an element in Ansys the EKILL command is used. You will need to select all elements in question to kill by the ESEL. This is what you have done in the APDL provided. However, could you check that without the EKILL, what is the state of your structure, may be all element have the strain below 0.2 from start so the EKILL will find NO element to select.
Check whether the elements are killed or not by simple GUI.
Select from main menu, Entities - Elements - Live Elem's.
