HS-1670: Set Up a Radioss Model
This tutorial demonstrates how to parametrize an input deck via HyperMesh and subsequently set up a Radioss model in HyperStudy.
Radioss simulations can be directly integrated into HyperStudy without any pre-processor such as HyperMesh. The integration takes place through interpreting variables in /PARAMETER cards in starter files. Thickness and Young's Modulus values will be the input variables of interest.
Add Parameters in HyperWorks
-
Launch HyperStudy and open the
TENSILE_TEST.hm file from your working directory.
Important: Verify the Profile is RADIOSS.
-
From the Model Browser, double-click the
SHELL1 property.
Tip: If necessary, you can enable the Model Browser from the menu bar by clicking .The Properties/PROP/SHELL Browser opens.
-
From the Properties/PROP/SHELL Browser, click
next to Thick and select from the context menu.
The Create Parameter dialog opens. -
In the Create Parameter dialog, enter
shell_th for the Name and click
Close.
Figure 1.
-
From the Model Browser, double-click the
MAT_LAW2_PLAS_JOHNS material.
The Materials/MAT/LAW2_PLAS_JOHNS Browser opens.
-
In the Materials/MAT/LAW2_PLAS_JOHNS Browser, click
next to E and select from the context menu.
The Create Parameter dialog opens. -
In the Create Parameter dialog, enter
Law_2_E for Name.

The Parameters are created.Figure 3.
- From the menu bar, click .
-
Export the solver deck as TENSILE_TEST_0000.rad to the
working directory.
You can open the solver deck in a text editor of your choice to view the parameters.

Set Up Radioss Model
- Start HyperStudy.
-
Start a new study in the following ways:
- From the menu bar, click .
- On the ribbon, click
.
- In the Add Study dialog, enter a study name, select a location for the study, and click OK.
- Go to the Define Models step.
-
Add the Radioss model by dragging-and-dropping the
TENSILE_TEST_0000.rad file from the Directory into the work area.
The Resource, Solver input file fields are populated.

-
Click Import Variables.
Two input variables are imported from the TENSILE_TEST_0000.rad file.
-
Go to the Define Input Variables step and review the
input variables.
