Generating energy models from scratch is a costly and time consuming task. A detailed energy model can have thousands of input parameters that are necessary for a complete simulation of a building. A solution to this problem is the AutoBEMGen framework.

For additive manufacturing of large-scale parts, significant part distortion can result from the build-up of residual stresses during deposition and cooling. This can result in part scarp if the final part geometry is not contained in the additively manufactured preform.

The heat exchanger is a three-medium heat exchanger with phase change material (PCM) stored in the external fin tubes. It allows the refrigerant flowing inside the internal fin tubes and the air to

Lean-burn natural gas (NG) engines are a preferred choice for the hard-to-electrify sectors for higher efficiency and lower NOx emissions, but methane slip can be a challenge.

In additive manufacturing large stresses are induced in the build plate and part interface. A result of these stresses are deformations in the build plate and final component.
