Upon conducting various tests, I have identified that the inability to open K files was not directly related to the use of DSG (Disc Sphere Generation). Instead, I discovered that the issue was attributed to the configuration within the Keyword "CONTROL_DISCRETE_ELEMENT."
Previously, I had entered only FRICS and FRICR as provisional values and set the Active option cards to None. This configuration prevented the successful opening of K files, as I found through my own experimentation.
While I am relieved that the problem has been resolved, I am curious as to why setting Active option cards to None would impact the ability to open K files. Is it due to my improper use of this Keyword? I would appreciate any insights or guidance you can provide on this matter.
Thank you for your assistance.
Best regards,
