Schematic representation of the spatial adaptivity. The coarse initial mesh (a) is first adapted based on the beam position (b). With the temperature distribution (c) the Kelly error indicator (d) is obtained. The equivalent viscoplastic strain distribution (e) is used for the mechanical error indicator (f). The indicators (d, f) are used for further refinement and coarsening. The elements with mechanical error indicator values \(\ge 0.8~ \mathfrak {e}^\text {m,max}\) are highlighted by a red outline
