Finite Element Analysis - The F3D file

Edit the F3D file and cut out all but the F3D model input section.

The F3D model begins with the section that begins with the “MATPROP” entry. It ends with the command “EvalAllMbrs”. Between are all the F3D entry fields (see list below).

Cut all BUT the F3D model from the file. This is now a run-able F3D file.

A F3D input file has these sections. Each section is self documented in the F3D file.

F3D Section	Description
MATPROP	Material properties
ELEPRP	Beam Element properties
PLTPRP	Simple FEM plates Use with caution. Not used in BRIDG.
NODE	Node location and constraint codes
MBR	Member nodes, material, section, and end releases
PLATE	Plate nodes
LDCASE	Load case names
NODELD	Nodal loads
MBRLD	Member loads
cmds	Commands to select load case and run
