Hi, Abaqus community!

I am trying to simulate a Resistance spot welding process in Abaqus/Standard by solving coupled thermal, mechanical and electrical physics. In my problem for a step no 3, I have set initial time of 0.05 secs and maximum time of 0.1 secs. I am using the default Abaqus time incrementation general solver settings in the simulation. However, the time incrementation is not increasing over successful iteration solve. I have attached a picture of the incrementation. The time incrementation is very low and its taking a very long time to solve the whole step. I will highly appreciate any suggestions to speed up the simulation.

Thank you,
