Thank you Reno,
The strain values are 0.04 compared to 0.12; however, the time series and shape are completely different. It does appear that contacts are causing the issue. There are 5 contacts, and we believe that the contact causing the issue is *CONTACT_SLIDING_ONLY_PENALTY for the contact between the brain and surrounding CSF.
Is there an equivalent contact that can be used for MPP or can the contact be configured to MPP?
Thanks again,
Colin
