Hey,

The contacts getting lost might not be due to midsurface creation entirely rather it can be due to contact setup.

If you are using midsurfacing tool try to create the surface which helps the contact. It can be done by selecting where you want the surface to be (not just mid surface)

Consider designating the contacting shell and target faces manually rather than leaving it to program controlled.

Consider using shell thickness effects as they help in considering shell thickness to detect contact.

Heres more help on that 9.6.3.1. Scope Settings (ansys.com)

If it still doesn't work try sharing the contact setup in the model.

Thanks
