Hi, I'm simulating welding process and I have negetive temperatures near the weld arc. the solution seems to be in heat capacity matrix used in default code in ABAQUS how can I manage the heat capacity matrix and change it from consistent form to lumped form.

hi corus, thanks for attention and reply I examined finer mesh and az u said the value of negetive temperature near the weld arc, reduced. but I read a paper on simulation (by L.E.Lindgren) that pointed out using lumped heat capacity matrix, instead of consistent heat capacity matrix to...

hi all, I'm trying to simulate the welding process. I've faced a problem... the temperature of some nodes that the heat source is to pass them next, get values like -138'C. and some times get to the absolute zero, and an error is the result. this nodal points are infront of weld pool on the weld...

hi bassmanjax, tnx for help, but would u tell me how I can speak or make consultation to the ABAQUS helpdesk? tnx again :-)
