Products: ABAQUS/Standard ABAQUS/Explicit
An infinite plate of width 0.1 unit and thickness 1 unit is considered. A zero flux boundary condition is imposed on all of the surfaces except the top surface. A film condition and sink temperature are imposed on the top surface, and the transient solution to the heat transfer problem is sought.
In ABAQUS/Standard the problem is modeled with 10 DC2D4 elements of dimension 0.01 × 0.01. In ABAQUS/Explicit two-dimensional (plane strain and plane stress) elements are used to model the plate: 10 elements are used through the width of the plate when using CPE4RT and CPS4RT elements, while 20 elements are used when using CPE3T and CPS3T elements.

In ABAQUS/Explicit dummy mechanical properties are prescribed to complete the material definition.
The transient solution at 
3600 units is plotted for all four cases; the finite difference solution is plotted as a solid line, and the three finite element results as markers at the centroid of the elements.
The results obtained with ABAQUS/Explicit are in close agreement with those obtained with ABAQUS/Standard.
