Computational steps
1. Process the mesh
The input data is written into the name.i1 text file.
Only the isoparametric elements, semi-loof elements, and the corresponding connector elements can be used. The fact that the sandwich and thermal contact resistance are not designed for static and dynamic problems must be taken into account when creating meshes for thermoelastic analyses.
| Program | XRM2 (2D problem) / XRM3 (3D problem) |
|---|---|
| Inputs | name.i1, alternatively name.NOD and name.ELE |
| Report | name.o1 |
| Outputs | binary files |
| Details | Computation overview, Mesh / Reference Manual: Inputs, Element Library, Input Syntax |
2. Process the material properties, boundary and initial conditions, and control parameters
The input data is written into the name.iB text file.
If a temperature field is available from a previous computation, it can be loaded directly from the name.TIC binary file (renamed name.TEM file).
| Program | XRPD (2D / 3D problem) |
|---|---|
| Inputs | name.iB, binary files from the previous step, name.TIC (optionally) |
| Report | name.oB |
| Outputs | binary files |
| Details | Computation overview, Material properties, Thermal boundary and initial conditions, Solver control parameters for steady-state linear analysis, Solver control parameters for steady-state nonlinear analysis, Solver control parameters for transient analysis / Reference Manual: Inputs, Quantities, Input Syntax |
3. Solve the equation system
The solver programs do not need any additional input data. The calculated temperature fields are written into the name.TEM binary file which can be used for a subsequent stress analysis.
Moreover, the name.STR text file with the results for the GFEM graphical postprocessor is written automatically.
| Program | XT2S (2D steady-state problem) / XT3S (3D steady-state problem) / XT2T (2D transient problem) / XT3T (3D transient problem) |
|---|---|
| Inputs | binary files from the previous steps |
| Report | name.oT |
| Outputs | name.STR, binary files (the solution is in the name.TEM file) |
