This project belongs to the heat transfer analysis type. The aim of this test case is to validate the following parameter using a transient thermal solver, with a surface and a convective heat flux boundary condition on a perforated plate:
The simulation results of SimScale were compared to the results presented in case B of [TTLP301]\(^1\).
The geometry used for the analysis with the highlighted node N1 can be seen below. It is a random thick plate with straight and curved edges.
The coordinates for each vertex of the plate are displayed in the following table:
Tool type : Code_Aster
Analysis type : Heat transfer, linear
Time dependency: Transient
Mesh and element types: Two mesh cases were considered for the analysis of the perforated plate, with 1st order and 2nd order tetrahedral elements:
|Case||Mesh type||Number of nodes||Number of 3D elements||Element type|
|(A)||Standard||5340||25676||1st order tetrahedral|
|(B)||Standard||16807||10976||2nd order tetrahedral|
Below, the 1st order tetrahedral mesh for case A is visualized:
The temperature values at node N1 for 12 time steps obtained with SimScale are compared against the results presented in case B of [TTLP301]\(^1\).
|Case A \([K]\)||Error [%]||Case B \([K]\)||Error [%]|
All of the cases are in good agreement with the reference results.
You can see the temperature distribution on the plate for the last time step for Case A below:
