Influence of dynamic shrinkage on pressure calculation
 
2 Attachment(s)
Hi All,

I have two almost identical calculations. The only difference is one is calculated with the dynamic shrinkage model the other without shrinkage. Both calculation show different pressure - from the very first step till the end (see attached images). Can anybody explain me this?

Best regards,
Johannes

Gravity pointed in another direction than the initial hydrostatic pressure. That seemd to be the reason for this strange behaviour.
