Hi, Everyone,
Could someone point me out what the problem would be inside this FEAP input file?

I should name the command as Boundary and Displacement, there is no E before that

EBOUndary and BOUNdary and DISPlacement and EDISpalcement are all meshing commands in FEAP.  See the user manual for descriptions of what then do, but in short EDISplacement and EBOUndary are convenience commands for setting displacements and boundary codes along nodes that all lie on a given coordinate plane (3D) or edge (2D).  BOUNdary and DISPlacement do the same thing but node by node.

Thanks for replying, But FEAP shows me an error like this; where do these errors come from, and how can I resolve them?

You did not correct your element cards correctly.  For your first element you have:

Code: [Select]

1 0 1 13117 13118 158 157 13119 13120 162 161
45517 45599 14193 45600 45521 13402 14200 13442
45522 45520 13602 14199From the manual, however, you are told

Code: [Select]

N, NG, MA, (ND_i, i=1,13)
(ND_i, i=14,29)
...
(ND_i, i=..,NEN)This means you should have

Code: [Select]

1 0 1 13117 13118 158 157 13119 13120 162 161 45517 45599 14193 45600 45521
13402 14200 13442 45522 45520 13602 14199So the first line has 3 numbers followed by 13 nodes (total of 16 items).  The second line as the remaining 7 nodes.
