Good day please assist in explaining the boundary conditions listed below.

*BOUNDARY

nall,3,3,0.0 i,e explain this condition_______________

1,1,3,0.0 i,e explain this condition_______________

2,1,3,0.0 i,e explain this condition_______________

*BOUNDARY

1,1,6,0.0 i,e explain this condition_______________

2,3,3,0.0 i,e explain this condition_______________

3,3,3,0.0 i,e explain this condition_______________

4,3,3,0.0 i,e explain this condition_______________

5,3,3,0.0 i,e explain this condition_______________

I have read the CalculiX manual, the difference between homogeneous and inhomogeneous boundary conditions

In my understanding

homogeneous boundary conditions can be defined as follows.

*BOUNDARY

1,1,2,3 (This means node 1, is fixed in x(1), y(2) & z(3) direction

inhomogeneous boundary conditions can be defined as follows.

that’s where i get confused how to prescribe a displacement, temperature etc.

I,e i see

*BOUNDARY

LINE3,1,1,0.0 (On line3 what does 1,1,0.0 mean? same as below)

LINE1,2,2,0.0
