Design Intent

Drill Press Table Displacement Image

You must decide which results are required to be viewed. Based on this decision you will create the visualization images and an analysis report which will clearly summarize the results of the computation. For this case study we will:

� Find the location of maximum value of translational displacement.

� Find the location of maximum values of Principal stress distributions.

� Find the location of maximum value of Von Misesstress in FE model.

� Find the location of maximum value of local error distribution.

� Create output sensors for Energy and Global Error Rate percentage.

� Create Resultant sensor to see the reactions at restraints.

� Create Analysis Report with Images.

Generating Images (2/2)

CATIA provides following types of result visualization images:

Visualize the computation error maps, which represent scalar field quantities defined as the distribution of energy error norm estimates for a given computation.

Precision

Visualize the Von Mises Stress field patterns, which represent a scalar field quantity obtained from the volume distortion energydensity and used to measure the state of stress. The volume distortion energy density is often used in conjunction with the material yield stress value to check part structural integrity according to the Von Mises criterion. For a sound structural design, the maximum value of the Von Mises stress should be less than this yield value.

Von Mises Stresses

Visualize the principal stress field patterns, which represent a tensor field quantity used to measure the state of stress and to determine the load path on a loaded part.

Principal Stresses

Visualize the displacement field patterns, which represent variation of position vectors of material particles as a result of applied load.

Displacement

Visualize the finite element mesh in the deformed configuration under the applied loading condition.

Using Sensors (1/2)

A sensor is a physical output of a computation. Sensors allow you to produce specialized output that is provided as a single value, rather than a range of values displayed on the model. You can use sensor output to:

A.Validate the Analysis resultsExample: Energy, Error in Energy, Global Error Rate sensors

B.Synthesize analysis results and thus use it as parameter to improve, optimize design specifications

Example: Maximum Displacement, Maximum Von Mises, Mass sensors

Provides mass in Kg.Mass

Provides Maximum Von Mises Stress value in N/m2.Maximum Von Mises

Global

Sensor Type

Provides Maximum Displacement Magnitude in mm.Maximum Displacement

Provides Global Error Rate in %.Global Error Rate (%)

Provides Error in Energy values in J.Error in Energy

Post-processing involves all those steps which are carried out after computation of results. In this step you will:� Create different images like Deformation,

Displacement magnitude, Stress, Reaction force, and other available images from computed solution data.

� Find location of result values in FE model.� Validate the results using different images and

study these images to understand and interpret the solution.

� Make decisions for further improving the solution with mesh refinement iterations or other solution types.

� Validate the current design or provide the changes based on the results.

Visualization ImagesCATIA provides the different visualization images to study the results of the analysis as shown in the table.

What is Post-processing

When you edit an image, you can choose the image type. Location of the result values, provided by the solver, changes according to the selected type. You can choose the location for text and symbol types only.

Stresses

To visualize computation error mapsPrecision

To visualize principal stress field patterns which represent a tensor field quantity used to measure the state of stress Principal Stresses

To visualize displacement field patterns which represent variation of position vectors of material particles

To visualize finite element mesh in the deformed configuration

Report Generation

After the required level of solution accuracy is reached, after and several mesh refinement iterations, you can generate reports.In this step of report generation, you will present the information generated during all stages of the FE Analysis process: Pre-processing, Computation, and Post-processing.

Sensors

Global sensor provides an output value for the entire FE model, while local sensor provides an output value for a local region in the FE model.

� Validate the Analysis Results� Synthesize the analysis results and use it as a

parameter to improve and optimize design specifications.

Sensor is a physical output of a computation. Sensors allow you to produce specialized output provided as a single value rather than a range of values displayed on the model.

You can use sensor output to:
