Hi, I have an assembly with multiple components connected via frictional contacts, After solving In workbench mechanical we generally get Contact Pressure and Frictional stress in the result. I understand these both relate to Contact Normal Force and Contact Traction force. However Insted of Pressure I want to evaluate the Contact Normal Force. Upon exploring I didn't find any method to do so. By some workaround how can it be calculated?

Hey,

Can you please check this post: How do I calculate force reactions (total XYZ force) for lots of contacts for all time points — Community Forum; Please make sure u turned "ON" Nodal Force. (Analysis Setting>Output Controls>Nodal Forces)

Thanks,

Deepak

Hi Deepak,Thanks for sharing the link to the discussion about evaluating Contact forces using DPF in ANSYS. This seems really helpful. I too was expecting integrating pressure with elemental area at the contact surface should help but didn't find any straightforward means to do the same in Mechanical.

I haven't used DPF features in ANSYS earlier which seems really interesting and I would like to learn more about it. Can you please share some resources from where I can start to learn more on using DPF? PS. I have intermediate experience in Python.

 

Best Regards,

Hi Prawal,

Data Processing Framework (DPF) for developers | Ansys Developer Portal; Examples — PyDPF-Post

If you have access to Ansys Learning Hub, search for “Introduction to Ansys Data Processing Framework – course“

Thanks,
