I need to implement a Fortran code using user subroutine in Abaqus for moving heat source model implementing volumetric gaussian laser heat source for multi-track laser scanning. I wrote code for a single track(bead) on a single layer for laser, Even it stopped working for 1 element. Now I need to write code for multi-track on a single layer. I need help regarding this. I didn't even find many resources for it.
AND ONE MORE THING IS SINCE I AM USING A VOLUMETRIC HEAT SOURCE, I SHOULD GIVE THE NAME OF THE VOLUME AS INPUT IN SYNTAX. WHAT SYNTAX IS USED FOR IT(for mentioning surface we use .SNAME=......... so for volume what should we use?)
