The encryption of solver entities is used to translate entity data into an undisclosed language. In HyperMesh, you can import and export encrypted material and curve entities when you are using the LS-DYNA user profile, and property and failure entities when you are using the RADIOSS user profile.

Support of encrypted solver entities will allow you, for example, to manipulate encrypted dummies within the Dummy browser.

You can view encrypted entities from the Model, Solver and XRef browsers. If an entity is encrypted, then the entities corresponding attributes will not be exposed anymore in Entity Editor or Card Panels, and curves cannot be reviewed or edited in the Curve Editor.

In HyperMesh version 14.0.120 and on, you can also encrypt the above mentioned solver entities inside the HyperMesh session when you are using the RADIOSS user profile.

You can undo and redo encryption actions made in a HyperMesh session using the Undo and Redo commands on the Restore toolbar.

When using the RADIOSS user profile, you are able to encrypt material, property, and failure model entities.

Encryption is supported by the encryption entity defined by the keyword /KEY.

Encryption in HyperMesh is available from the Solver browser.

1.In the Solver browser, right-click on an entity card and select Encrypt from the context menu.

encrypt_entity

2.In the Encrypt Window dialog, create a new encryption entity or select an existing encryption entity from the list. You can also enable entities linked to the selected entity to be encrypted at the same time, for example, failure models and/or material functions linked to a material model.

3.Click Encrypt.

Encrypted entities are marked with the key icon (icon_key) in the Solver browser.

When encrypting an entity in the Encrypt Window dialog, you can create new encryption entities.

1.In the Encryption Window dialog, right-click on the EncryptionID field and select Create from the context menu.

create_encryption

In the Create Encryptions dialog, an encryption key is automatically created.

2.Click Previous to go back to the Encrypt Window dialog or click Close to close the encryption process without encrypting the entity.
3.When you return to the Encrypt Window dialog, click Encrypt to encrypt the selected entities after all needed encryption keys have been defined.

 

 

Notes

If a RADIOSS deck contains an entity that was previously encrypted in a HyperMesh session, it will be imported into a new HyperMesh session and you will not be able to “decrypt” it and retrieve the entities attributes. It may be useful to create a copy of the entity before you encrypt it.

The presence of encrypted entities in a RADIOSS model will disable the solver conversion capabilities from RADIOSS to OptiStruct or RADIOSS to PAM-CRASH2G.
