Of course it's appears to be different as you introduced Joint loads and OFFSETS. These were not stated in your initial statement which was as follows;
"I need held regarding the following:
Model details:
Slab (plate elements) resting on beam (member) on one long side only. Supports; fixed at both ends.
Slab size: 4m x 2m x 1m; Mesh size 0.2m x 0.2m
Beam length: 4m (split in to size of 0.2m length), Section size 200mm x 200mm
Load: Self wt of slab only
Problem:
The support reactions and the beam end forces do not match at the supported nodes.
Thanks."
Which area you want me to look at?
