Query: Fast explicit dynamics finite element algorithm for transient heat
  transfer   This paper presents a novel methodology for fast simulation and analysis of
transient heat transfer. The proposed methodology is suitable for real-time
applications owing to (i) establishing the solution method from the viewpoint
of computationally efficient explicit dynamics, (ii) proposing an element-level
thermal load computation to eliminate the need for assembling global thermal
stiffness, leading to (iii) an explicit formulation of nodal temperature
computation to eliminate the need for iterations anywhere in the algorithm,
(iv) pre-computing the constant matrices and simulation parameters to
facilitate online calculation, and (v) utilising computationally efficient
finite elements to efficiently obtain thermal responses in the spatial domain,
all of which lead to a significant reduction in computation time for fast
run-time simulation. The proposed fast explicit dynamics finite element
algorithm (FED-FEM) employs nonlinear thermal material properties, such as
temperature-dependent thermal conductivity and specific heat capacity, and
nonlinear thermal boundary conditions, such as heat convection and radiation,
to account for nonlinear characteristics of transient heat transfer.
Simulations and comparison analyses demonstrate that not only can the proposed
methodology handle isotropic, orthotropic, anisotropic and
temperature-dependent thermal properties but also satisfy the standard patch
tests and achieve good agreement with those of the commercial finite element
analysis packages for numerical accuracy, for 3-D heat conduction, convection,
radiation, and thermal gradient concentration problems. Furthermore, the
proposed FED-FEM algorithm is computationally efficient and only consumes a
small computation time, capable of achieving real-time computational
performance, leading to a novel methodology suitable for real-time simulation
and analysis of transient heat transfer.
