DATABASE_CROSS_SECTION_SET - Problem

[Kağan GENÇ]

Hello everyone,

I am trying to crate a database that I can see some cross sectional forces. However, I got the error seen below in the picture. I created SET_BEAM which includes all nodes for beam sections but I could not find to get rid of that error. Can anyone help me to solve that ?

Error:

 Beginning of keyword reader                                   02/03/21 20:57:55

 *** Error 10363 (KEY+363)

     Cross section 1 requires a node set definition.

 *** Error 10363 (KEY+363)

     Cross section 1 requires a node set definition.

 *** Error 10133 (KEY+133)

     input data failed with: 4 errors

Dear Kagan,

See if this helps:

Forces can be obtained a variety of ways:

• You can obtain interior forces and moments at a cross-section via the commands *DATABASE_CROSS_SECTION and *DATABASE_SECFORC. Note that when the "set" option is used in defining a cross-section, a node set identifying the path of the cross-section AND at least one element set identifying the elements to ONE SIDE of the cross-section must be provided.
• You can obtain externally applied forces on nodes or groups of nodes via the commands *DATABASE_NODAL_FORCE_GROUP and *DATABASE_NODFOR.
• You can obtain forces associated with boundary conditions via the command *DATABASE_BNDOUT.
• You can obtain forces specifically associated with *BOUNDARY_SPC by including the command *DATABASE_SPCFORC.
• Resultant contact forces are written via the command *DATABASE_RCFORC. In the case of single surface contact, you would also need *CONTACT_FORCE_TRANSDUCER_(option) to extract resultant contact forces generated by the single surface contact.
• Contact forces on individual nodes are written via *DATABASE_NCFORC. One or both of the "print flags" SPR, MPR in *CONTACT must be set to 1 to identify the areas where nodal contact forces are to be extracted.

The data is written into the ASCII files SECFORC, NODFORC, BNDOUT, SPCFORC, RCFORC, and NCFORC.
