This validation case belongs to heat transfer, with the case of a half square column subjected to the imposed temperature gradient. The aim of this project is to demonstrate the validity of SimScale’s Heat Transfer solver by replicating the standard test case and comparing the following parameters:
The simulation results from SimScale were compared to the reference results presented in the standard EN-ISO 10211, validation case 1 (Annex C)\(^1\).
The half square column is illustrated in Figure 1:
The column has dimensions of 2 x 1 x 0.1 \(m\), forming a half-square.
Tool Type: Code_Aster
Analysis Type: Heat Transfer
Mesh and Element Types:
The mesh was computed using SimScale’s Standard meshing algorithm, with the fineness parameter maxed up to 10. Statistics of the resulting mesh are presented in Table 1, and illustration shown in Figure 2:
|Mesh #||Mesh Type||Element Type||Number of Nodes||Number of Elements|
|1||Standard||1st order tetrahedrals||273345||1431857|
The reference solution for the half square column is of the analytical type. It is presented as the computed temperatures in \(°C\) at a set of points located in a 7×4 equidistant grid across the column (28 points). The reference values are presented in Table 2:
The computed temperature values in SimScale are presented in Table 3:
Results show that, up to one decimal place of precision, the values computed by SimScale match the theoretical values presented in the standard. The acceptance criterion states that the difference between the computed temperatures by the method being validated and the listed temperatures shall not exceed 0.1\(°C\). Thus, it is found that the SimScale solver is accepted under the standard’s validation case 1.
