Hii guys,

i am trying to simulate rc slab under heat transfer but i am facing this type of error "Solver problem. Zero pivot when processing D.O.F. 1 of 8 nodes. The nodes have been identified in node set WarnNodeSolvProbZeroPiv_1_1_1_1_1."

i dont know if this error has a relation with the type of constraint of the model, and if if i should define a type of constraint , what should be ??

thank you a lot ..

regards,
