Use the Conversion tool to convert an OptiStruct file to a LS-DYNA file.
1. | Load the OptiStruct user profile. |
2. | Import an OptiStruct model. |
3. | To run the conversion macro, from the menu bar, click Tools > Convert > OptiStruct > To LsDyna. The Conversion tab opens. |
4. | For Destination template, select the destination solver version. |
5. | To start the conversion, click Convert. After the conversion, the LS-DYNA user profile automatically loads. |
6. | Review and export the deck using the LS-DYNA user profile. Some of the keywords in the OptiStruct deck are converted to the LS-DYNA deck as per the following tables. |
