Thank you so much I will get back to you

How to get such results by applying a user defined numerical criteria

Thank you but it how to include the calculation of critical stress based on MPS.

I am working on welding simulation for cold crack prediction in the welding of molybdenum. It is a thermomechanical simulation, and cracks develop when the Principal Stress stress exceeds the critical stress, especially in the cooling step when the temperature drops to room temperature...

How to impliment my own criteria in abaqus using a subroutine. When critical stress exceeds the MPS then crack would occur.

spring not working does any one help me please?

Do I need some changes in LOAD/Boundary condition in after applying spring through interaction????

`Abaqus has spring element but how to use them as boundary condition it is a challenge for me. How to put them to avoid rigid body motion.

e.g. workpiece is clamped in welding or AM process at the end of simulation I want to remove clamp but dont want to allow rigid body motion due to high temperature. four spring at corners may help to achieve this but I could not realize a spring boundary condition.

I need urgent guidance to apply spring as a boundary condition to avoid rigid body motion.

I am using DFLUX subroutine in ABAQUS for moving laser heat source in AM simulation. One track is successfully simulated with heat source but when ever I tried for multi track with TIME(2) it does not work. Need urgent guidance. Thank you
