Abstract :
    In this research, the numerical investigation of time-dependent 2D heat transfer in A36 low-alloy marine sheets is carried out. The numerical simulation is performed by ABAQUS software and once again by coding in MATLAB software; then, the results of these both methods are analyzed. Coding in MATLAB included defining assumptions, creating geometry, connecting the boundary nodes, and finally solving the partial equations. Using temperature-dependent/independent data, simulation in ABAQUS included two modes of transient and steady-state conditions. After the solution is obtained in this two software, temperature contours of the whole domain were presented. In the ABAQUS simulation, six different mesh systems composed of different square and triangular elements with fine and coarse granules are considered. An average of 1.25 % error was calculated for the highest temperatures of specified points for these different mesh systems. Furthermore, when using temperature-dependent heat capacity and heat coefficient parameters, temperature values showed significant differences from those of the temperature-independent mode.
