Example 70: Stress Analysis Using Results (Pressure) Imported from Fluid Analysis

General

• The results (pressure) of Example 7 of fluid analysis are imported for the stress analysis.
   

• Deformation and mechanical stress of the fan blades due to the air pressure are analyzed.
   

• Unless specified in the list below, the default conditions will be applied.

 

• Obtain this session's project file. (Right-click and choose 'Save link as')
  
  

• Results will vary depending on Femtet version and the PC environment.

The project file contains a model for fluid analysis (Fluid) and a model for stress analysis (Stress).

 

Analysis Conditions

To import the results of fluid analysis, set Pressure as an import type, Fluid as an import model, and Automatic as an import mode on the result import tab.

By setting Automatic as an import mode, the results at the final time are imported.

Results

The deformation diagram is shown below. The air pressure is applied from the +Z direction and the fan blades are deformed in the -Z direction.
