SQP and DEM set up difference

Hello,

I am trying to solve a problem using both DEM and SQP. I am seeing that when I am using SQP some parameters are deactivated. In SQP, only Hertzian collision model is available. Also, I cannot choose the Spring Constant in SQP. I am attaching the screenshots of the two set up. Kindly have a look and let me know why I cannot activate some model settings in SQP that I used in DEM simulations.

I look forward to hearing from you.

Thanks and Regards,

Debashis

Those options are disabled deliberately because they are not implemented or appropriate for the SQP model.

Thank you for the clarification Dr. Waldman.
