SubscriberI have been running a number of simulations involving 4 bodies (assume 3 parts are bonded, 1 interface assumes friction).
Sometimes I have noticed the solver fails to display pressure across a body (even though there is 100% pressure present). This sometimes happens, so I was just wondering what is causing this?
By the way, it does show me frictional stress and SX, SY, SZ, and all other solution components (just not pressure, displaying a blue bar marked 0). Note that the vice versa has occured in the past, but I can overcome issues with friction displayed using the normal stress component.
I originally thought it was related to which section I assigned as 'contact' and 'target' - however, this error has just reoccurred, and I was using the same settings as before, so I don't know what has caused the zero pressure display now.

SubscriberAre there CONTA175 elements in your model?

SubscriberYes I believe so - I have 4 bodies, and I want to look at the surface pressures on one of the bodies. They do make full contact and I've assumed the surface in question to be bonded with another surface

SubscriberHi again - just to clarify, the surface-surface contact has only been applied to body faces (not nodes/edges)
