Although you can view the deformed shape, SimScale does not have the feature to download the deformed shape yet. However, you can still download the results, which already includes the information regarding the deformed mesh. With third-party software, such as ParaView, you can export the deformed mesh as a CAD model.
This article explains the procedure for downloading the results and viewing them in ParaView.
Having said that, in SimScale, you do not need to download the results to view the deformed shape of your model. You can do this in the post-processor, by activating the Displacement filter:
If the deformation is too small, the difference will be too small for you to see. In order to visualize the deformation better, you can scale the displacement. This is accessible in the post-processor settings.
