Introduction To Section Creation In RADIOSS

The purpose of creating the section is to understand how the force waves travel around a section. The sections at different components give a broad idea of peak force generated at a particular instant of time. This tool is very handy and helpful in understanding in-depth the simulation results. Some of the options available in the section menu are discussed below.

What is DeltaT?

DeltaT is the time to start saving the sectional forces data. The unit of DeltaT is ‘s’. A minimum value of 0.1 must be inputted in the place of deltaT only then the forces at the sections are properly captured and saved. This option can also be interpreted as the time to activate the capturing of the section’s force results.

Steps To Create a Section In Radioss

Step 1

Open the section option using the solver > create > SECT > SECT option

Step 2

Now let's create a moving frame for the section. To create a moving frame, Solver > Create > Frame > Mov

Step 3

Let's get back to the already created cross-section. Select the origin node, X-axis direction and XY plane. This can be created based on the global coordinate system.

Step 4

In the SECT option, First, select the frame that is already created and assign it to the section

Step 5

Select the required shell elements using the grshel_id option. Right-click on it > create > in the new dialog box select the required elements by clicking on the entity id as elements.

The reason is to cover the whole area of the component properly.

Step 6

Enter the values for Isave, deltaT and alpha.

And Voila, you have created the section. Now to obtain the results from the section, create an output block. Select the entity as a cross-section and select the above-created cross-section.
