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 Radioss (Block Format). The Conversion tab opens. |
4. | To start the conversion, click Convert. After the conversion, the selected version of the RADIOSS user profile automatically loads. |
5. | Review and export the deck using the RADIOSS user profile. Some of the keywords in the OptiStrut deck are converted to the RADIOSS deck as per the following tables. |
