We also need to right click on the Setup cell in the External Model block and select Update to get a green checkmark in that cell: This establishes the link from the NASTRAN model to the new Modal analysis. Next, we drag and drop the Setup cell from the External Model block onto the Model cell of the Modal analysis block. You set it up as a separate block and establish the link in the next step. Note that you can’t drop this onto the Setup cell in the External Model block as you might expect. Next, I drag and drop a new analysis type block into the Project Schematic.
I then click the … button to browse to the NASTRAN input file. Once I have the NASTRAN input file that I need to convert into ANSYS Mechanical, I launch ANSYS Workbench 16.0 and insert an External Model branch. Instead, I created a model in ANSYS, then converted it into NASTRAN using ANSYS FE Modeler to get a NASTRAN input file for the purpose of this exercise.) (Note that we don’t have NASTRAN here at PADT, so I couldn’t create a generic sample of a NASTRAN model in NASTRAN. Here is an example of this new procedure. However, this new technique can be an incredible time saver in addition to giving us capabilities to continue and augment simulations that were previously performed in NASTRAN, now in ANSYS. As with most translations from one FE tool to another, you can’t expect everything will be translated. In fact, not only can you move the NASTRAN model into ANSYS Mechanical, but you get the existing mesh as well as newly-created geometry that can be used for boundary condition application, etc. bdf) that you need to get into ANSYS Mechanical, no longer do you have to use FE Modeler in ANSYS Workbench to perform the translation. If you happen to have a NASTRAN input file (.dat. I found another very nice enhancement to version 16.0 of the ANSYS Workbench/ANSYS Mechanical toolset.
