Use the Fatigue panel to write stress, strain, force, and moment results from finite element analysis to an external file that can then be used to set up fatigue analysis.
Stress/strain results are used for fatigue analysis of shell/solid elements, while force/moment results are used for fatigue analysis of spot welds. You may choose to write these results for the entire finite element model or for selected entities.
There are no subpanels on the Fatigue panel. All inputs and command buttons are located on the main panel.
Input |
Action |
FE Analysis Type: static-modal / transient dynamic |
Use static/modal if the finite element analysis stress/strain results were obtained from linear static or modal analysis. Use the transient dynamic option if dynamic finite element analysis was used to obtain the stress/strain results for the model. |
Output File Format: ascii /binary |
Select the file format, depending on the format supported by the fatigue solver. |
entity selector |
Select elems, comps, nodes, or sets. You must choose nodes if the data group that you selected pertains to nodal results. Similarly, you must choose elements if the data group you selected pertains to elemental results. Alternatively, a predefined entity set comprised of nodes or elements can be selected pertaining to a data group with nodal/elemental results, respectively. If the results of the data group and the entity type are not the same, HyperMesh displays the error message "Results file doesn’t contain nodal (or elemental) values." |
output file |
Use the browse button to locate an output file name and location. This file becomes the input file for the fatigue solver. |
data group |
Select from the available data groups the one you want to write to the output file. For more information on data groups, please see Fatigue Configuration File. |
select simulation |
Select from all, selection, or range. You can write out stress/strain information for all of the time steps, or you can choose a range from a starting time step to an ending time step, or you can choose a selection of time steps manually from the available list. |
start with |
Select the time step to start the simulation. |
end with |
Select the time step to end the simulation. |
The following action buttons appear:
Button |
Action |
write |
A file in the specified format (ASCII or Binary) is written to your directory. You can read this file into the appropriate fatigue solver to complete the setup for fatigue analysis. |
return |
Exits the panel. |
