Thermal Solver for parts

  Is there a way to turn the thermal solver on for some parts/elements and off for others in a model? Or every part need to be involved?
  Thank you.

  Hello Chenxi,
  If you want some parts to not take part in the thermal solution in LS-DYNA, define BOUNDARY_TEMPERATURE for all the NODES belonging to the PARTS to be removed. You can set the temperature to anything. Temperature=0 is a reasonable choice. These nodes will then be constrained out of the problem. You will still need to assign a thermal material to these parts though.
