Opening and Saving Files - HM-1010

In this tutorial, you will learn how to:

Exercise 1: Opening and Saving Files

This exercise uses the following model files: bumper_cen_mid1.hm, bumper_mid.hm, bumper_end.igs, and bumper_end_rgd.fem. Each model fie contains various sections, but the whole bumper model is shown, following.

Step 1: Open the HyperMesh model file, bumper_cen_mid1.hm.

The model file, bumper_cen_mid1.hm, is now loaded. This file contains mesh and geometry data.

HyperMesh model file, bumper_cen_mid1.hm, opened in HyperMesh

• Open a HyperMesh file

• Import a file into a current HyperMesh session

• Save the HyperMesh session as a HyperMesh model file

• Export all the geometry to an IGES file

• Export all the mesh data to an OptiStruct input file

• Delete all data from the current HyperMesh session

• Import an IGES file

• Import an OptiStruct file to the current HyperMesh session

1. Access the Open File … dialog in one of the following ways:

• From the Pull-down menu , choose File , then Open

• From the Standard toolbar , click Open ( )

2. Open the model file, bumper_cen_mid1.hm.

Step 2: Import the HyperMesh model file, bumper_mid.hm, into the current HyperMesh session.

The file, bumper_mid.hm, is now imported into the session.

Step 3: Import the IGES geometry file, bumper_end.igs, into the current HyperMesh session.

Geometry data is added to the model.

1. Access the Import tab in one of the following ways:

• From the Pull-down menu , choose File , then Import

• From the Standard toolbar , click Import ( )

2. From the Import tab in the tab area, choose Import type: HM Model from the pull-down menu.

3. Under File selection , click the file icon ( ) and browse to select the file, bumper_mid.hm.

4. Click Apply .

1. From the Import tab in the tab area, choose Import type: Geometry from the pull-down menu.

2. Under File selection , choose File type: Iges from the pull-down menu.

3. Under File selection , click the file icon ( ) and browse to select the file, bumper_end.igs.

4. Click Apply .

Step 4: Import the OptiStruct input file, bumper_end_rgd.fem, into the current HyperMesh session.

This OptiStruct input file contains mesh for the bumper’s end portion. The mesh is added to the existing data in the current HyperMesh session and will be located in the same area as the geometry representing the bumper’s end.

1. From the Import tab in the tab area, choose Import type: FE Model from the pull-down menu.

2. Under File selection , choose File type: OptiStruct from the pull-down menu.

3. Under File selection , click the folder icon in File: and browse to bumper_end_rgd.fem.

4. Click Apply .



OptiStruct input file, bumper_end_rgd.fem, imported on top of data in the current HyperMesh session

Step 5: Save the HyperMesh session as a HyperMesh model file called practice.hm.

The data currently loaded in HyperMesh is now saved in a HyperMesh binary data file of the name you entered.

Step 6: Export the model’s geometry data to an IGE S file called practice.igs.

All of the geometry loaded in HyperMesh (points, lines, surfaces) is now saved in an .iges file with the name you entered.

Step 7: Export the model’s mesh data to an OptiStr uct input file called practice.fem.

1. From the File pull-downmenu, select Save As...

2. Enter the name, practice.hm.

3. Click Save.

1. Access the Export tab in one of the following ways:

• From the Pull -down menu , choose File , then Export .

• From the Standard toolbar , click Export ( ).

2. In the Export tab, choose Export type: Geometry from the pull-down menu.

3. Under File selection , File type: should indicate Iges .

4. Under File selection , click the folder icon in the File field, browse to the desired destination folder, and enter practice.igs

5. Click Save.

6. Click Apply to export the file.



All of the finite element data loaded in HyperMesh (nodes, elements, loads, etc.) is now saved as an .fem file with the name you entered.

Step 8 (Optional): Delete all data from the curren t HyperMesh session.

Step 9 (Optional): Import the IGES geometry file y ou created, practice.igs.

Refer to Step 3 for detailed instructions.

Step 10 (Optional): Import the Optistruct input fi le you created, practice.fem, into the current HyperMesh session.

Import practice.fem into the current session. The data in the file will be added to the existing data in the current HyperMesh session. Refer to Step 4 for detailed instructions.

With the completion of Steps 8, 9, and 10, your current HyperMesh session should contain all of the geometry and mesh data that existed in the HyperMesh session that was saved to a HyperMesh file in Step 5.

Step 11 (Optional): Save your work.
