| 1. | Load the Nastran user profile. |
| 2. | Import a Nastran model. |
| 3. | To run the conversion macro, from the menu bar, click Tools > Convert > Nastran > To Ansys. The Conversion tab opens. |
| 4. | To start the conversion, click Convert. After the conversion, the ANSYS user profile automatically loads. |
| 5. | Review and export the deck using the ANSYS user profile. Some of the keywords in the Nastran deck are converted to the ANSYS deck as per the following tables. |

If the model contains Nastran elements which were mapped to MASS21, LINK8, COMBI14, BEAM44, SHELL63, SHELL93, SOLID45 and SOLID95 elements, respective ETTYPES will be created and assigned to the component. Key options of ETTYPE will not be updated.
If the component collector contains different type of configuration of elements, new components will be created for the respective configurations and those elements will be moved into the new component. ETTYPE, material and realset IDs will be assigned to the new component.
Loads and boundary conditions will not be converted by using this conversion tool.
