Thank you for your prompt response.
If WB LS-DYNA refers to ANSYS Workbench, I would like to clarify that I am not using it. My current tools of choice are LS Prepost and LS Run.
When attempting to open a K file in LS PrePost, it freezes as depicted in the attached image. However, for verification purposes, I tried opening a simple K file created in the past, and it opened successfully.
Lately, I have been creating models using Disc Sphere Generation (DSG). Could this be the reason why I am unable to open files? Interestingly, as shown in the image below, the model displays correctly when opened in 2020R.
Is there any solution or workaround for this issue? Your assistance is greatly appreciated.
