Finite element with joint and muscle forces

dear anybody

Hello, I always had "Too many attempts made for this increment" with ABAQUs when I did finite element analysis of joint and muscle forces derived from anybody, including the Clavicula model in the help document. In addition, when I use femur model to do analysis, I found that the "joint force and muscle force" I exported were concentrated on the femur head, rather than scattered on the whole femur, I tried many times and failed, can you help me analyze what reason is, thank you!!
