is EKILL during simulation possible?
(OP)
hi,
I am trying KILL the nodes that come up with very high temperature, as they stop the program from running to its completion.. or even modify the temperature to melting point temperature
What I am trying to do is simulate submerged arc welding (the object is complete insulated). When I apply a heat flux, no matter how small it is, it comes up with nodes that have 10e6 or more temperature, which stops the analysis. The only way it work now is when i assign ONE node to a particular temperature.
i would appreciate any help that anyone could provide.
Thank you
Robin

RE: is EKILL during simulation possible?
if I have correctly understand, you want to kill nodes DURING THE SOLUTION - that means, during the solve command. If that is the case, that´s not possible. You have to decide which ELEMENTS (not nodes) you want to kill before you solve.

CODE
esln,s
elis
The "elist" command will list the elements attached to the node 12345.

may be, you could try running the transient thermal analysis on suffieciently fine time intervals in a *DO loop:
the first time step solution -> checking temperatures in POST1 and EKILL the melted elems -> thermal restart, the second time step sol. ->....
Be sure that you do not kill the heat source too (probably must be moved to "living" parts).
