HS-1025: Working with a HyperMesh and HyperMorph Model

 Previous topic Next topic JavaScript is required for expanding text JavaScript is required for the print function  

In this tutorial you will learn how to import size and shape variables to HyperStudy from HyperMesh. The input variables are three shape variables; xtrans, ytrans and radius. Each of these shapes are created by perturbing the mesh in the corresponding directions by 1 unit.

The sample base input template used in this  tutorial can be found in <hst.zip>/HS-1025/. Copy the tutorial files from this directory to your working directory.

1.Start HyperStudy.
2.To start a new study, click File > New from the menu bar, or click files_new_hst2 on the toolbar.
3.In the HyperStudy – Add dialog, enter a study name, select a location for the study, and click OK.
4.Go to the Define Models step.
5.Add a HyperMesh model.
a.From the Directory, drag-and-drop the plate_with_shapes.hm into the work area.

b.In the Solver input file column, enter plate.fem. This is the name of the solver input file HyperStudy writes during any evaluation.
c.In the Solver execution script column, select OptiStruct (os).

6.Click Import Variables.
7.In the Model Parameters dialog, select parameters to import into HyperStudy.
a.Select the thickness and shape variables. A total of 6 parameters should be selected.
b.Click Add.
c.Click OK.

8.Go to the Define Input Variables step.
9.Review the input variable's lower and upper bound ranges.
10.Go to the Specifications step.

1.In the work area, set the Mode to Nominal Run.
2.Click Apply.
3.Go to the Evaluate step.
4.Click Evaluate Tasks.
5.Go to the Define Output Responses step.

 
hmtoggle_plus1greyStep 3: Create and Define Output Responses

In this step you will create two output responses: Mass and Displacement.

1.Create the Mass output response.
a.From the Directory, drag-and-drop the plate.out file, located in approaches/nom_1/run_00001/m_1, into the work area.
b.In the File Assistant dialog, set the Reading technology to Altair® HyperWorks® and click Next.
c.Select Single item in a time series, then click Next.
d.Define the following options, and then click Next.
•Set Type to Mass.
•Set Request to Mass.
•Set Component to Value.

e.Label the output response Mass.
f.Set Expression to First Element.
Note:Because there is only a single value in this vector, [0] is inserted after v_1, thereby choosing the first (and only) entry in the vector.

g.Click Finish. The Mass output response is added to the work area.
2.Create the Displacement output response.
a.From the Directory, drag-and-drop the plate.h3d file, located in approaches/nom_1/run_00001/m_1, into the work area.
b.In the File Assistant dialog, set the Reading technology to Altair® HyperWorks® and click Next.
c.Select Single item in a time series, then click Next.
d.Define the following options, and then click Next.
•Set Subcase to Subcase 1 (Load).
•Set Type to Displacement (Grids).
•Set Request to N298.
•Set Component to MAG.
e.Label the output response Displacement.
f.Set Expression to First Element.

g.Click Finish. The Displacement output response is added to the work area.
3.Click Evaluate to extract the output response values.
