Hi..


I am doing a solids contact simulation using impactBar as a template.


When I am using same material for the complete geometry, I can see the areaContact field is increasing as expected.


However when I am assigning materials to cellZones, the areaContact field remains zero. For both the trials I used the same mesh where there is a contact. The assigned cellzones had density lower that the initial trial of same material throughout.



I had initialized with DD, DD_0, DD_0_0, DD_0_0_0, and the similar D fields same as impactBar tutorial. But only when I am using a homogenous material the contact is solved.


So should I be assigning different DD values for different materials? I understand DD is just V * delT, but I only faced this issue when the material assign are different.
